Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,



Cross multiply


Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5
Answer:
4, 4√3
Step-by-step explanation:
In a 30-60-90 triangle:
The leg opposite of the 30-degree angle is 1/2 of the hypotenuse: 8/2 = 4
The longer leg is √3 times the shorter leg: 4*√3 = 4√3
Check work: 4^2+(4√3)^2 = 8^2 --> 16+48 = 64 --> 64 = 64
Answer:
$819
Step-by-step explanation:
First we find the area of the wall so we multiply 13ft x 9ft.
13ft x 9ft = 117ft
We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.
117 x 7 = $819
Answer:
d. 266cm^2
Step-by-step explanation:
SA=2lw+2lh+2hw
It's an irrational number which means the number never ends and has no pattern in its decimal. So you would round it:
9/6.5= 1.384615384615385
but the answer would be 1.384
