Question

Find the value of x and the measure of the angle labeled 3x.

Answer 1

Answer:

the answer is D, x= 10;angle measure is 30°

Answer 2

Answer:

D

Step-by-step explanation:

3x and 30 are vertically opposite angles and congruent, then

3x = 30 ( divide both sides by 3 )

x = 10 , thus

3x = 3 × 10 = 30°

x = 10 ; angle measure is 30° → D
