Answer 1

Answer:

this is very easy just take the ratio as 3x 4x 5x and divide by 180 for more explanation message me

Answer 2

Answer:

45°, 63°, 72°

Step-by-step explanation:

Let the angles A,B and C be 5x, 7x and 8x respectively.

Sum of all the three angles in triangle = 180°.

=> 5x + 7x + 8x = 180°

=> 20x = 180°

=> x = 9°.

Thus the angles of triangle are 5 * 9 , 7 * 9, 8 * 9 = 45°, 63°, 72°
