PLEASE HELPPP ILL GIVE BRAINLIESTTTT

Answer 1

Answer:

8

Step-by-step explanation:

The interior angles of a triangle always add up to 180°.

As QE=ED=QD

so, ∠Q=∠E=∠D=180°/3=60°

As, ∠D=5x+20

60=5x+20

5x=40

x=8

Hope, this helps you.

Answer 2

Answer:

x= 8

Step-by-step explanation:

QE=ED=QD

SO;

Sum of angles =180

each angle = 60

5x+20= 60 —> 5x =60-20 —> 5x = 40

x = 40/5 —> x = 8

I hope I helped you^_^
