Question

2 angles of triangle are 3 times and 5 times of the first angle. find all the angles of the triangle ​

Answer 1

Answer:

Step-by-step explanation:

Answer:

The angles of the triangle are 30° , 60° and 90°

Step-by-step explanation:

Given :

Two angles of a triangle are two times and three times the first angle.

To find :

all the angles of the triangle

Solution :

Let the first angle be x°

Two times the first angle = 2x°

Three times the first angle = 3x°

Concept : The sum of all the three angles of the triangle is equal to 180°

x° + 2x° + 3x° = 180°

6x° = 180°

x = 180°/6

x = 30°

The first angle = 30°

2x = 2(30°) = 60°

3x = 3(30°) = 90°

Therefore, the angles of the triangle are 30° , 60° and 90°

Know More :

As one of the angles of the triangle is 90°, the triangle is a right angled triangle.

Answer 2

Answer:
20°,60°,100°

Step-by-step explanation:

LET ONE ANGLE BE= x

ACC. TO QUESTION,
OTHER 2 ANGLES WILL BE= 3x, 5x

sum of all angles of triangle = 180 (angle sum property)
x+3x+5x = 180
9x = 180
x = 180/9
x = 20°
3x = 3×20 = 60°
5x = 5×20 = 100°
