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)
C because 3x is three times x and it equals 3x^2
