Question

3. The angles of a triangle are in the ratio of 1: 1:2. Find the measure of each angle,​

Answer 1

Answer:

1st angle = 1x = 45°

2nd angle = 1x = 45°

3rd angle = 2x = 45 × 2 = 90°

Step-by-step explanation:

Ratios = 1 : 1 : 2

Sum of all the angles in a triangle = 180°

= 1x + 1x + 2x = 180

= 4x = 180

= x = 45

1st angle = 1x = 45°

2nd angle = 1x = 45°

3rd angle = 2x = 45 × 2 = 90°

Answer 2

Answer:

x=45 degree

x=45 degree

2x=45x2=90 degree

Step-by-step explanation:

Let the angles be x, x and 2x.

Since the sum of all the angles =180 degree

x+x+2x=180 degree

Or, 4x=180 degree

Or, x=(180/4) degree

Or, x=45 degree

Now, the angles are

x=45 degree

x=45 degree

2x=45x2=90 degree
