Question

One angle of a traingle is 30. The other two angles satisfy the condition that one of the angles is twice the other angle. What are the angles? ( A ) 60, 120 ( B ) 45, 90 ( C ) 50, 100 ( D ) 40, 80

Answer 1

Answer:

C

Step-by-step explanation:

Let 1 angle be x

another angle=2x

x+2x+30= 180

3x=150

x=50°

2x=100°

Answer 2

Answer:

C)  50° , 100°

Step-by-step explanation:

Let one of the angles be x.

The other angle will be 2x .

We know that sum of all angles in triangle = 180

=> x + 2x + 30 = 180°

=> 3x = 150

=> x = 50°

One Angle = 50°,

The other angle = 2x = 2 * 50 = 100°
