Question

Find the unknown measures. Round lengths to the nearest tenth and angle measures to the nearest degree. EF= DE= ∡D= degrees

A) EF = DE = ∡D = 90°
B) EF = DE = ∡D = 45°
C) EF = DE = ∡D = 60°
D) EF = DE = ∡D = 120°

Answer 1

EF = DE = ∡D is equal to 90°.

Step-by-step explanation:

The question states that EF = DE = ∡D. Since all three measures are equal, we can use any of them to find the value. Let's choose ∡D = 90° as an example. Since the measures are equal, EF and DE must also be equal. Therefore, EF = DE = 90°.
