Question

Can you guys help me please

Answer 1

Angle ace is 80 degrees

Answer 2

Angles ACD and ACE are supplementary. They combine to form a straight angle which is 180 degrees. Let x be the measure of angle ACE.

----

(angle ACD) + (angle ACE) = 180

100 + x = 180

x = 180-100 .... subtract 100 from both sides

x = 80

angle ACE is 80 degrees
