Question

find the value of x :-
∆A=2x
∆B= x
∆C=3x​

Answer 1

Answer:

2x+x+3x=180

6x=180

x=30

A=60

B=30

C=90

Answer 2

Step-by-step explanation:

some of the angles of a triangle = 180°

∆A + ∆B + ∆C = 180°

2x + x + 3x = 180°

6x = 180°

x = 180° / 6

x = 30°

∆A= 2 × 30 = 60°

∆B = 30°

∆C = 3 × 30 = 90°
