Answer:
7.9
Step-by-step explanation:
the first thing to do is find the second projection.
16-7 = 9
than we can use a proportion to find BD
7 : BD = BD : 9
BD = √9 x 7 = √63 = 7.9
we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2

To find:
The measures of missing angle [tex]m\angle K, m\angle M[/tex].
Solution:
In the given figure [tex]JK\parallel ML[/tex].
If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.
[tex]m\angle J+m\angle M=180^\circ[/tex] (Supplementary angles)
[tex]87^\circ+m\angle M=180^\circ[/tex]
[tex]m\angle M=180^\circ-87^\circ[/tex]
[tex]m\angle M=93^\circ[/tex]
Similarly,
[tex]m\angle L+m\angle K=180^\circ[/tex] (Supplementary angles)
[tex]51^\circ+m\angle K=180^\circ[/tex]
[tex]m\angle K=180^\circ-51^\circ[/tex]
[tex]m\angle K=129^\circ[/tex]
Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].

Step-by-step explanation:
The speed of the truck, s, must be no less than 34 miles per hour
is s ≥ 34.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, The speed of a truck, s, must be no less than 34 miles per hour.
Therefore, The speed of the truck must be greater than or equal to 34 miles per hour.
So, The inequality that represents this context is,
s ≥ 34.

What would the measure of the third angle
equal?
Answers
Answer:
55
Step-by-step explanation:
180−43−82=55(angles of a triangle add upto 180)
What would the measure of the third angle equal?
Well given that all 3 vertices of a triangle are supposed to be a sum of 180*
Hence this information side E is 82* and side H is 43* and when added up they equal 125 so then you would subtract 180 - 125 = 55\
Therefore, side T = 55*
A 9-foot (ft) ladder and a 4-foot ladder are leaning against a house. The two ladders create angles of the
same measure with the ground. The 4-foot ladder has a height of 3.8 feet against the house.
Help please!!
Answers
Answer:
The 9-foot ladder would have a height of 8.55 ft against the house
Step-by-step explanation:
The angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.
The situation forms a right angle triangle.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angle can be found using trigonpometric ratios.
Therefore, the 9 foot and the 4 foot ladder forms the same angle.
The 4 foot ladder forms a 3.8 ft height against the wall.
Hence,
sin ∅ = opposite/ hypotenuse
sin ∅ = 3.8 / 4
∅= sin⁻¹ 0.95
∅ = 71.8051276612
∅ = 71.8°
Therefore, the angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.

A telephone pole casts a 32-foot shadow, while a street sign next to the pole casts a 12-foot shadow. If the
telephone pole is 40 feet tall, what is the height of the street sign?
12
Answers
Answer: The height of street sign = 15
Step-by-step explanation:
At the same time, the angle made by the light on each object is the same.
Pole and street sign both standing vertical to the ground.
So triangle made by both of them are similar
The sides of similar triangles are proportional,
[tex]\dfrac{\text{height of street sign}}{\text{height of pole}}=\dfrac{\text{Length of the shadow made by street sign}}{\text{Length of the shadow made by pole}}\\\\\dfrac{\text{height of street sign}}{40}=\dfrac{12}{32}\\\\\text{height of street sign}=\dfrac{12}{32}\times40=15[/tex]
Hence, the height of street sign = 15
The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the larger number and y represent the smaller number. Which equations represent this situation?
Answers
Answer:
y= -x
y= 3/2 -5
Step-by-step explanation:
The sum of two numbers is zero.
x + y = 0
y = -x
Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5
