Question

Two angles of a triangle are in the ratio2:3 and its third angle is 70 degree .Find other two

angles of the triangle​

Answer 1

Answer:

Given : ratio= 2:3

So, Let the angles be 2x and 3x

So, the three angles are 2x,3x and 70°

We know that, sum of angles of a triangles is 180°

so, 2x + 3x + 70° = 180°

or, 5x +70° = 180°

or, 5x = 110°

or, x= 22°

Therefore the two angles =

2x = 2*22° = 44°

3x = 3*22° = 66°

Hope it helps you :-)

Answer 2

Answer :-

44° and 66°

Explanation :-

Given :

• Two angles of a triangle are in the ratio 2:3.
• Third angle is 70°

To Find :

• Other 2 angles.

Solution :

Let the angles be 2x and 3x.

We know that,

Sum of all angles in Triangle = 180°

➞ 2x + 3x + 70 = 180°

➞ 5x + 70 = 180°

➞ 5x = 180 - 70°

➞ 5x = 110°

➞ x = 22°

Therefore, The Angles are :-

• 2x = 44°
• 3x = 66°
