Question

find the measure of each angle of the three angles on a straight line if 2 of them are equal and third is twice of both​

Answer 1

Answer:

45°,45°,90°

Step-by-step explanation:

Let equal angles be x then third angle = 2x

x+x+2x=180  (straight line = 180°)

4x=180°

x=45°

2x=90°

Answer 2

Answer:

x= 45°, x= 45°, 2x= 90°

Step-by-step explanation:

Given,

Let, the two equal angles be x then third angle =2x. Now, x+x+2x= 180° [ Sum of angles of straight line ] = 4x= 180° = x= 180° ÷ 4 = x= 45°. Therefore, x= 45° = 2x= 2×45° = 90.
