Which option shows the measure of the unknown angle,x and how to find it
Answer:
E) 37
Step-by-step explanation:
The total measurement for the angle ABC is 90 as it is a right angle.
Add your known angles together and substract from 90 to get your unknown.
90 - 21 - 32 = 37
Answer:
E. Subtract 21 and 32 from 90, x=37
Step-by-step explanation:
Since there are 90 degrees in a right angle, we can find the missing angle by adding the two angles we have together and then subtracting the sum from 90.

What are the values for X-ray satisfy the equation
X^2 - 5(x) - 14 = 0
A. -2 and 9
B. -2 and -9
C. 2
D. 2 and -7
E. -2 and 7
Answer:
It's D
Step-by-step explanation:
you just look at the end it's says -14. u have to see what numbers should multiply in order to get negative 14, you can use -2 and 7, or -7 and 2, but you have to see what numbers from the -14 will add up -5 because u have five in there, therfore -7+2 equals -5.* This only happens if you have 1 behind the x^2.
?????? Cos ?? I don’t know the difference between cos and tan fully yet , but ASAP help here
The answer is M
Step-by-step explanation:
Cosine: this is the length of the side right next to the angle divided by the longest side/ hypotenuse.
Tan: this is the length of the side opposite of the angle divided by the side directly adjacent/ next to the angle.
In this case, cosine would be 6/10 which Is also 3/5. the angle right next to 6 is Angle M

Si los dos triángulos ABC y DFE son proporcionales, ¿Cuál será la longitud del lado DE del triángulo DFE?
Answer:
La respuesta esta abajo
Step-by-step explanation:
Un triángulo es un polígono con tres lados y tres ángulos.
Se dice que dos triángulos son proporcionales si la razón de sus lados correspondientes está en la misma proporción.
de la pregunta, el lado AB es proporcional a DF, AC es proporcional a DE y BC es proporcional a FE
Por lo tanto, dado que ambos triángulos son proporcionales, entonces:
DE / DF = AC / AB
x / 10 = 21/15

Edward took a survey of his classmates to see how many pets each student has. The dot plot shows the results of his survey ll. 0 1 2 3 4 Number of Pets Part A How many people did Edward survey? Part B What is the mean number of pets?
Answer:
i. 5 people
ii. Mean number of pets = 2
Step-by-step explanation:
i. From the information given in the question, the number of people surveyed by Edward is 5.
The first person has no pet, the second has 1 pet, the third has 2 pets, the fourth has 3 pets and the fifth has 4 pets.
ii. The mean number of pets is the average number of pets among the people.
The mean number of pets = [tex]\frac{sum of the number of pets}{number of people}[/tex]
= [tex]\frac{0 + 1 + 2 + 3 + 4}{5}[/tex]
= [tex]\frac{10}{5}[/tex]
mean number of pets = 2
The mean number of pets is 2.

Answer:
384, 216, 290, 192, 384
1446, 1 roll
Step-by-step explanation:
For rectangular boxes, calculate the sum of each side, then multiply it by two.
Box 1: 2(18 x 5) + 2(18 x 4) + 2(5 x 4) = 364
Box 3: 2(11 x 8) + 2(8 x 3) + 2(3 x 11) = 290
Box 5 is a cube (all sides equal), so you can find 1 side's area and multiply it by 6.
Box 5: 6(8 x 8) = 384
For triangular boxes, calculate the edges, then find the triangular area using area = 0.5(base x height).
Box 2: (15 x 3) + (9 x 3) + (12 x 3) + 2(0.5)(9 x 12) = 216
Box 4: 2(13 x 2) + (10 x 2) + 2(0.5)(10 x 12) = 192
Total: 364 + 290 + 384 + 216 + 192 = 1446
Rolls of wrapping paper:
Area of 1 roll = 30 x 60 = 1800
Since 1446 is less than 1800, you only need 1 roll of wrapping paper.

Explain how to factor the following:
16x^2 – 40x – 24
Answer: (x-3)(2x+1)(8)
Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.

Step-by-step explanation:
true or false dialations of an angle are congruent to the original angle
Answer: True
Step-by-step explanation: Dilations do not change the angle measure. All line segments are changed by the same factor, therefore the angle remains the same.
Given the function f(x) = 0.65x + 117, what
s the x-value of the zero?
Answer:
x = -180
Step-by-step explanation:
0 = 0.65x + 117
-117 = 65x/100
cross-multiply to solve for 'x':
65x = -11700
x = -11700/65
x = -180
