Question

the measur of two angles of a triangle are 72 and 58 find the measure of the third angles​

Answer 1

We know that

sum of angle of triangle= 180

given

two angle of a triangle is 72 and 58

let the third angle B

angle B + 72 + 58= 180

angle B = 180 - 130

angle B = 50

Answer 2

Answer:

perimeter of triangle = a+b+c

180= 72+58+c

180=130+c

c=180-130

c=50 answer
