Question

Q.5 The angles of the triangle are in the ratio 3 : 4 : 5. Find each of these angles.​

Answer 1

Answer:

Angles are in the ratio of 3:4:5

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

∴3x+4x+5x=180

Sum of the angles of triangle are 180 degree

∴12x=180

∴x=15

Hence, the angles are: 45 ,60∘,75 ∘

Answer 2

Step-by-step explanation:

sum of all angles in traingle is 180

so,here from traingle sum rule,

3x+4x+5x=180

12x=180

x=15

so angles are 45°,60° ,75°
