Question

If angles A, B, and C of the triangle ABC, taken in order, are in the ratio 3 : 7 : 8, then find the

angles.​

Answer 1

Answer:

30, 70, 80

Step-by-step explanation:

Let's angle as 3x, 7x, 8x

3x + 7x + 8x = 180

18x = 180

x = 10

angle 1 = 3x = 3*10 =30

angle 2 = 7x = 7*10 =70

angle 3 = 8x = 8*10 =80

Answer 2

Hey mate here's your answer -:

Let the angles be 3x, 7x and 8x. Now, We know -:

Sum of angles of a triangle = 180°

Angle 1 + Angle 2 + Angle 3 = 180°

3x + 7x + 8x = 180°

18x = 180°

x = 180 ÷ 18

x = 10°

Angle 1 = 3x = 3×10 = 30°

Angle 2 = 7x = 7×10 = 70°

Angle 3 = 8x = 8×10 = 80°
