Answer: the measure of ∠TSU is 61 degrees.
Step-by-step explanation:If ∠RST and ∠TSU are complementary angles, it means that their measures add up to 90 degrees.
Given that m∠RST is 29 degrees, we can use this information to find the measure of ∠TSU.
To find the measure of ∠TSU, we subtract the measure of ∠RST (29 degrees) from 90 degrees, because the sum of complementary angles is 90 degrees.
90 degrees - 29 degrees = 61 degrees.
