Question

I need help fast thank you all!!

Answer 1

b = 5.2

c = 3.5

Explanation:

By 45°- 45° - 90° triangle theorem:

`c = (1)/( √(2) ) * 5 \\ \\ c = (1)/( 2) * 5 √(2) \\ \\ c = 2.5 * 1.414\\ \\ c = 3.535 \\ \\ c \approx \: 3.5`

By 30°- 60° - 90° triangle theorem:

`b = ( √(3) )/(2) * (2 * 3) \\ \\ b = 3 √(3) \\ \\ b = 3 * 1.732 \\ \\ b = 5.196 \\ \\ b \approx 5.2`
