The figure shows a square, a regular pentagon and a regular hexagon put together. What is the measure of ∠BAC

Sagot :

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°
