What is the sum of the measures of two complementary angles?
m∠ Y=55^(∘)
We have been given a pair of complementary angles Y and Z. We know that the measure of Z is 35^(∘). Let's take a look at a graph representing this situation.
Since the angles are complementary, we know that the sum of their measures should equal 90^(∘). We can solve for measure of Y by creating an equation using the measures of the two smaller angles and their sum.
We found that the measure of ∠ Y equals 55^(∘).
