Question

If the measure of ∠D is 53 degrees and ∠D and ∠E are complementary, what is the measure of ∠E?

Answer 1

`\angle E = 37^o`

Explanation:

In order to find the measure of ∠E, we will set up an equation.. But before we do that, we will take a look at what we're given.

given : -

∠D and ∠E are complementary

that means : -

∠D + ∠E = 90 ,since the sum of two complementary angles is always 90 degrees

The measure of ∠D is 53 degrees, therefore:

53 + ∠E = 90

∠E = 90 - 53 = 37

therefore ,the measure of angle E is 37 degrees.
