Question

hi, I'm in 7th grade. i have to submit this assignment.
please help me ​

Answer 1

Answer:

x=65°

y=40°

Step-by-step explanation:

In fig 1 x=65°

explanation:sum of interior angles of a triangle is 180°.

therefore x=180-(65+50)=65°

in fig 2:y=40°

explanation:The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.

therefore y=120-80=40°

Answer 2

Answer:

1. 65° + 50° + x = 180° (sum of all angles of a triangle)

115° + x = 180°

x = 180° - 115°

x = 65°
