Question

in a triangle the largest angle is 20 degree more than the smallest angle the third angle is 10 degree more than smallest what is themeasure of smallest angle

Answer 1

Answer:

smallest angle = 50°

Step-by-step explanation:

smallest angle = x

third angle = x+10

larger angle =x+20°

by angle sum property

angle 1 + angle 2 +angle 3=180°

x + (x+10) + (x+20) = 180°

x+x+x+10+20=180°

3x+30=180°

3x=180-30

3x=150°

x=150÷3

x=50
