Answer:
![x=20.6\ in](https://tex.z-dn.net/?f=x%3D20.6%5C%20in)
Step-by-step explanation:
we know that
Applying the Pythagoras Theorem
![41.2^{2} =35.7^{2} +x^{2}](https://tex.z-dn.net/?f=41.2%5E%7B2%7D%20%3D35.7%5E%7B2%7D%20%2Bx%5E%7B2%7D)
solver for x
![x^{2}=41.2^{2}-35.7^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D41.2%5E%7B2%7D-35.7%5E%7B2%7D)
![x^{2}=422.95](https://tex.z-dn.net/?f=x%5E%7B2%7D%3D422.95)

Changing a fraction to its decimal form can be done by long division method. Dividing the denominator by its numerator will change the fraction into decimal form. Alternatively, you can use a calculator to do that for you. Below are the fractions with their decimal forms listed:
1.) 2/5 = 0.4 (D)
2.) 7/20 = 0.35 (A)
3.) 3/25 = 0.12 (C)
4.) 7/10 = 0.7 (B)
Answer:
9. a) 180 - (55+90) = a
b) a=35 degrees
10. a) 2w + 3w + 40 = 180
b) w=28
c) 2w=56 3w=84
