Question

Please help ! I am bad at math :(

Answer 1

Angle CBA and CBE create a straight angle so they add up to 180.

CBA + CBE = 180
155 + CBE = 180
CBE = 25

Hope this helps :)

Answer 2

The angles ∠ABC and ∠CBE together should equal 180º.
∠ABC is 155º.
180 - 155 = 25
So, ∠CBE = 25º.
Hope this helps!
