Question

Find the measure of the angle indicated

Answer 1

Answer:

65°

Step-by-step explanation:

The missing angle of the left hand side triangle is

180 - 78 - 38 =

180 - 116 = 64°

The bottom left angle of the right hand side triangle is

180 - 64 - 61 =

180 - 125 = 55°

The top angle of the right hand side triangle is 60°, by vertical angle theorem.

The missing angle is:

180° - 55° - 60°=

180° - 115° = 65°

Answer 2

Answer:

65°

Step-by-step explanation:

First find the angle in the triangle by

78+38 =116 then subtract it by 180 gives 64

after add 64 with 61 gives 125 then again subtract it from 180 again which gives you 55

And as you can already see that 60° side at the top is same with the inner angle, so from there you

55° + 60° = 115°

180°- 115° = 65°
