Question

One of the angles of a triangle is twice the other angle if the third angle is 100 degree find the other angles, pls provide steps too

Answer 1

Answer:

Angles ≈ 26.66° and 53.33°

Step-by-step explanation:

Let the angles be x and 2x respectively.

So,

=> x + 2x + 100 = 180° (sum of all angles of a triangle)

=> 3x = 180 - 100

=> 3x = 80

=> x = 80/3

Angles = >

1. x = 80/3 ≈ 26.66°
2. 2x = 160/3 = 53.33°

Answer 2

Answer:

3x+100=180

x=80/3= the first angle

the second angle = 2x=160/3
