Question

out of the three anglea of a Triangle , the second angle is 45 degree more than the smallest angle. the third angle is three times the smallest angle.find all the angles of the triangle.​

Answer 1

Answer:

27°, 72°, 81°

Step-by-step explanation:

Let the smallest angle be x.

2nd angle = x + 45

3rd angle = 3x

We know that sum of all angles in triangle = 180

x + x + 45 + 3x = 180

5x = 180 - 45 = 135

=> x = 27°.

Thus the angles of triangle are 27°, (27° + 45°) , (3 *27°)

     = 27°, 72°, 81°

Answer 2

x+45+x+3x=180°

5x+45=180°

x=27°

x+45=72°

3x=81
