Question

Angles of a triangle are in the ratio 3:4:5 . Find each angle

Answer 1

Answer:

LET THE ANGLE BE X

SO THE ANGLES ARE 3X + 4X + 5X

THE SUM OF ANGLE OF TRIANGLE IS 180

SO, 3X + 4X + 5X = 180

12X = 180

X = 15

so, 3x = 15×3 = 45

4x = 15×4 = 60

5x = 15×5 = 75

plz mark me as brainlest and plz follow me

Answer 2

Hello!!

The total measure of all the angles of a triangle is 180 degrees.

Given,

3x + 4x + 5x = 180 degrees

12x = 180 degrees

x = 180\12

= 15

So,

3x = 15 × 3 = 45 degrees

4x = 15 × 4 = 60 degrees

5x = 15 × 5 = 75 degrees

Hope it helps you!!!
