Question

in triangle abc angle ∠a=x+30° ∠b=3x+40° ∠c=x+10° find ∠a,∠b,∠c steps

Answer 1

Answer:

as we know sum of all angles of a triangle equals 180°

so,

a+b+c = 180°

(x+30°) + (3x+40°) + (x+10°) = 180°

5x + 80° = 180

5x = 100°

x = 20°

Answer 2

/_à=30°,/_b=120°,/_c=30°

Step-by-step explanation:

Measurement of triangle = 180°

x+30°+3x+40°+x+10=180°

30°+120°+10°x'2'=180°

160°-180

20°

10°+20°=30°
