Question

The angles of triangle are in the ratio 3:4:5 find the meassure of each the angles​

Answer 1

Answer:

45 degrees, 60 degrees, 75 degrees

Step-by-step explanation:

let the angles be 3x, 4x, 5x

sum of all angles of a triangle = 180 degrees

3x + 4x + 5x = 180

12x = 180

x = 180/12 = 15

3(15), 4(15), 5(15) = 45, 60, 75

Answer 2

3 + 4 + 5 = 12

we know the sum of triangle is 180°

3 × 180/12 = 45° first angle

4 × 180/12 = 60° second angle

5 × 180/12 = 75° third angle

Hence the angles are 45° , 60° and 75°

let proof that ; we know the sum of triangle is 180

first angle + second angle + third angle = 180

45 + 60 + 75 = 180

180 = 180

Hence Proofed!!

Hope it helps!!
