Add: 5 + 3 = 8
Exponentiation: the result of step No. 1 ^ 2 = 8 ^ 2 = 64
Add: 32 + 2 = 34
Subtract: the result of step No. 2 - the result of step No. 3 = 64 - 34 = 30
Multiple: 5 * the result of step No. 4 = 5 * 30 = 150
Add: 8 + the result of step No. 5 = 8 + 150 = 158

Answer:
42
Step-by-step explanation:
One angle of a regular pentagon = 108°
One angle of a regular hexagon = 120°.
One angle of a square = 90°
∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°
