Step-by-step explanation:
a^2 + b^2 =c^2
13^2+b^2= 37^2

b= 34.6
Answer:
Q19 - x = 7
Q20 - x = 24
Step-by-step explanation:
Q19.
75 + x + 8 = 90°
83 + x = 90°
x = 90 - 83
<u>x = 7</u>
<u>{</u>CHECK: 75 + 7 + 8 = 90°<u>}</u>
<u></u>
Q20.
3x - 6 + x = 90°
4x - 6 = 90°
4x = 96
x = 96 / 4
<u>x = 24</u>
<u>{</u>CHECK: 3(24) - 6 + 24 = 90°<u>}</u>
<u></u>
