Answers
Answer:
22.5°
Step-by-step explanation:
We know that the measure of straight line is 180° . Therefore the sum of all angles will be 180° .
⇒ 90° + x + 3x = 180°
⇒ 90° + 4x = 180°
⇒ 4x = 90°
⇒ x = 90°/4
⇒ x = 22.5°
Hence the value of x is 22.5°Related Questions

insert 7 arithmetic means between 4 and 8
Answers
Answer:
mafi mallum
Step-by-step explanation:
The 7 arithmetic means between 4 and 8 are
9/2, 5, 11/2, 6, 13/2, 7, and 15/2.
What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
First term = 4
This means,
a = 4
9th term = 8
This means,
a + (9 - 1)d = 8
4 + 8d = 8
8d = 8 - 4
8d = 4
d = 4/8
d = 1/2
Now,
2nd term = 4 + (2 - 1)1/2 = 4 + 1/2 = 9/2
3rd term = 4 + 2 x 1/2 = 4 + 1 = 5
4th term = 4 + 3 x 1/2 = 11/2
5th term = 4 + 4 x 1/2 = 4 + 2 = 6
6th term = 4 + 5 x 1/2 = 13/2
7th term = 4 + 6 x 1/2 = 4 + 3 = 7
8th term = 4 + 7 x 1/2 = 15/2
Thus,
The arithmetic sequence is 4, 9/2, 5, 11/2, 6, 13/2, 7, 15/2, 8.

Pamela is 14 years younger than Jiri. The sum of their age is 70. What is Jiri’s age?
Answers
Answer:
56 ...
Step-by-step explanation:
70-14 = 56
Since it’s the sum of their age it’s just jiri’s age plus Pamela’s so you just subtract Pamela’s age from the total sum. And that would make jiri 56. (Sum means the total from adding) So if you do the problem over again. “The sum of 56 and 14” it would take you back to the question you have now. This is inverse addition.
Answer:42
Step-by-step explanation: you split 70 in half, 35 and 35. Then you add 7 to one (Jiri) and subtract 7 from one(Pamela). You get 42 and 28. To check you do 42-28=14 and 42+28=70.

There are 4 points that form a rectangle. Three of the points are: (-5 -1) (-5 3) (2<3 What are the coordinates of the fourth point?
Answers
Answer:
[tex]C = (2,-1)[/tex]
Step-by-step explanation:
Given
[tex]A = (-5,-1)[/tex]
[tex]B = (-5,3)[/tex]
[tex]D = (2,3)[/tex]
Required
The coordinate of the fourth point (C)
The given coordinates indicate the rectangle is vertical/horizontal because it has similar x and y values.
The coordinate of such rectangle can be represented as:
[tex]A = (x_1,y_1)[/tex]
[tex]B = (x_1,y_2)[/tex]
[tex]C = (x_2,y_1)[/tex]
[tex]D = (x_2,y_2)[/tex]
By comparing the general coordinates with the given coordinates, we have:
[tex]x_1 = -5[/tex] --- see A and B
[tex]y_1 = -1[/tex] --- see A and C
[tex]x_2 = 2[/tex] ---- see C and D
[tex]y_2 = 3[/tex] --- see B and D
So, we have:
[tex]C = (x_2,y_1)[/tex]
[tex]C = (2,-1)[/tex]

Ryan needs 20 feet of cable. The longest piece on her truck is 18 3/8 feet. How many feet too short is the cable on the truck? *
Answers
Answer:
1 5/8 too short
Step-by-step explanation:
The cable on the truck is 18 and 3/8 ... to complete the fraction into a whole number we would need 5 more parts in order to complete the entire 8 parts of the fraction. This would make the cable a whole 19 feet. Since Ryan needs 20 ft, this would leave us needing 1 more foot. Therefore, the cable in the truck is
1 5/8 too short
Find an equation for the inverse for each of the following.
Answers
Answer:
To solve these first swap x and y, solve for y and name it inverse function3. y = -8x + 2
x = -8y + 28y = -x + 2y = -x/8 + 2/8y = -(18)x + 1/4f⁻¹(x) = -(18)x + 1/4
-----------------------------------------
4. y = (2/3)x - 5
x = (2/3)y - 5(2/3)y = x + 5y = (3/2)x + (3/2)5y = 1.5x + 7.5f⁻¹(x) = 1.5x + 7.5
-----------------------------------------
5. f(x) = 2x² - 6
x = 2y² - 62y² = x + 6y² = 1/2x + 3y = [tex]\sqrt{1/2x + 3}[/tex]f⁻¹(x) = [tex]\sqrt{1/2x + 3}[/tex]
-----------------------------------------
6. y = (x - 3)²
x = (y - 3)²[tex]\sqrt{x}[/tex] = y - 3y = 3 + [tex]\sqrt{x}[/tex]f⁻¹(x) = 3 + [tex]\sqrt{x}[/tex]

A construction crew is lengthening a road. The road started with a length of 54 miles, and the crew is adding 4 miles to the road each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use the equation to find the total length of the road after the crew has worked 39 days
Answers
Answer:
54 + 4D = L
After 39 days, the total length of the road will be 210 miles.
Step-by-step explanation:
Given that a construction crew is lengthening a road, and the road started with a length of 54 miles, and the crew is adding 4 miles to the road each day, to write an equation in which L represents the total length of the road ( in miles), and D represent the number of days the crew has worked, and then use the equation to find the total length of the road after the crew has worked 39 days, the following calculations should be performed:
54 (initial length) + 4D = L
54 + 4D = L
Thus, if the crew worked 39 days, the equation would be applied as follows:
54 + 4x39 = L
54 + 156 = L
210 = L
Therefore, after 39 days, the total length of the road will be 210 miles.

That chart is confusing ash, but median just refers to the middle value. Just put them in order (4,4,6,9,12) and then find the middle. In this case it's easy as there are an odd number of values. But if you have another question where there are an odd number, for example (4,4,6,10,12,15) find the two middle numbers, 4 and 9, add them (6+10=16) and then divide by 2 to find the number in between those two. (16/2=8)
