Okay the answer is 69 because 81-2 is 69
Answer:
What is the height of each triangle side?
Step-by-step explanation:
Answer: -1000, 27r^21, g^3h^30, and -1
Step-by-step explanation:
6 mm
Set up a proportion of 12/9=8/x. Cross multiply and this gives us 12x=72. Now divide both sides by 12 and you get 6.
You have to work out the area of each side. The two identical triangles are 6x4=24 because 8/2 is 4. The base is 8x5=40. The back is 6x5=30 and the top is 10x5=50. You then add them all together to get 144 ft squared.
