Question

one of the angle of a triangle is 60 degree the different between the other two angle 20 degree,then the measure of smallest angle is​

Answer 1

Answer:

A=60°

Step-by-step explanation:

B - C=20°

B=20+C

Now, in a triangle

A +B+C=180

putting values

60°+20°+C+C=180

80°+2C=180

2C =180-80°

2C=100

C=100/2

C=50°

and

given,

B-C=20

B-50=20

B=20+50

B=70°

hence, the smallest angle of triangle is angle C
