Question

BRAINY HELP ME THE ANGLES OF A TRIANGLE ​ ARE (3x) degree (2x-7) and (4x - 11)​

Answer 1

Answer:

The angles are:- 66⁰ ,37⁰, 77⁰

Step-by-step explanation:

First Step:- make the formula

3x + 2x-7 + 4x-7 = 180⁰(total angles in a ∆ add upto 180⁰)

Second Step:- make 'x' the subject

9x-18= 180

9x= 180+18

x= 198÷9

x= 22

Third Step:- Substitute '22' instead of 'x'

3(22)= 66⁰

2(22)-7= 37⁰

4(22)-11= 77⁰
