Answer:
The measure of angle ∠ b is 68°.
Step-by-step explanation:
There are two angles ∠ a and ∠ b which are complementary.
Therefore, from the definition of complementary angles, we have
∠ a + ∠ b = 90°
Now, if the angle ∠ a is measured to be 22°, then
22° + ∠ b = 90°
⇒ ∠ b = 90° - 22°
⇒ ∠ b = 68°
Therefore, the measure of angle ∠ b is 68°. (Answer)

Answer:
The sum of interior angles of a regular shape is found by doing no. of sides - 2 and times this by 180
8-2 =6
6x 180= 1080
then divide by 8 to find each angle
1080/8 = 135
