Answer: x = 7
`Step-by-step explanation:
Because the figure shows two triangles that are similar. we can write and solve an equation of ratios:
9 cm 72 cm
----------- = -----------
3x - 20 56 cm
Cross-multiplying, we get (3x - 20)(72 cm) = (9 cm)(56 cm) = 504 cm²
Dividing both sides by 72 cm, we get:
3x - 20 = (504 cm²) / (72 cm) = 7
Then 3x - 20 = 7, and 3x = 27. Then x must be 9.
Answer:
x=3
Step-by-step explanation:
Answer:
560 cubes
Step-by-step explanation:
width: 8 cubes
length: 10 cubes
height: 7 cubes
volume: 8*10*7=560
divided l, w, and h by 1/3 to get them in cubes
Answer:
h = √(44) ft
Step-by-step explanation:
Just looked back and A is actually the area because the unit was ft².
Area of a right isosceles triangle is half the area of a square.
A = ½S²
in this case your side is h.
A = ½h²
2A = h²
√(2A) = h
√(2(22)) = h
√(44) = h
plug that in your calculator for the answer.
