Question

what is the measure of the missing angle? m∠edg=? enter the number of degrees.

Explanation:

Step1: Identify angle - type

We know that ∠EDF is a right - angle, so ∠EDF = 90°.

Step2: Use angle - subtraction

We want to find ∠EDG. Given ∠GDF = 20°. Since ∠EDF=∠EDG + ∠GDF, then ∠EDG=∠EDF - ∠GDF.

Step3: Calculate the angle

Substitute the values: ∠EDG = 90° - 20° = 70°.

Answer:

70
