Question

if two angles are given in a triangle (113'30) find the measure of third angle​

Answer 1

Answer:

sum total of three angles of traingle is 180°

so, two angles are 113° and 30°

so, the third angle is = 180°- (113+30)°

so, the third angle is = 97°

Answer 2

Answer:

37 degrees

Step-by-step explanation:

take a triangle ABC

angle A is 113 degrees

angle B is 30 degrees

angle C is unknown

and as we know by the angle sum property

A+B+C=180 degrees

113+30+C=180

143+C=180

C=180-143

C=37 degrees
