Answer:
x =5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of one triangle over the same side of the other triangle.
x 4
------ = ----------
40 32
Using cross products
32x = 4*40
32x = 160
Divide each side by 32
32x/32 =160/32
x =5
Answer:
3/4

If Frank earns $12 an hour and works 3 hours a week, he makes $36 a week. So for 7 weeks, he earns $252 because $36x7 weeks= $252 in 7 weeks
From triangle AED we can find the length of a side of ABCD
AD=(4^2+4^2)^(1/2) (pythagorean theoerem)
AD=32^(1/2)
For similar reasons as applied to the triangle AC=(2AD^2)^(1/2)
AC=(2*32)^(1/2)
AC=64^(1/2)
AC=8
