Question

14 In ∆ABC, If ∠A=2x-5⁰, ∠B=5x+50, ∠C=3x+50⁰, then find the value of x.​

Answer 1

Answer:

Step-by-step explanation:

a = 2x-5

b = 5x+5

c = 3x + 50

a + b + c = 180

2x-5 + 5x + 5 + 3x +50 = 180

10x + 50 = 180

10x = 130

x = 13

a = 2*13 - 5 = 21

b = 5*13 +5 = 70

c = 3*13 +50 = 89
