Question

find the measure of each angle of a triangle​

Answer 1

Answer:

Angle A = 60 degrees

Angle B = 70 degrees

Angle C = 50 degrees

Step-by-step explanation:

the angle of a straight line is 180 degrees..

so the exterior angle B is 110 degrees

to find angle B = 180-110

= 70 degrees

exterior angle C is 130 degrees

to find angle C = 180-130

= 50 degrees

According to Angle Sum Property, all angles total upto 180 degree

so to find angle A (let angle A be x)

180 = 50 + 70 + x

180 = 120 + x

x = 180 - 120

= 60 degrees

hope you're satisfied with the answer :)
