Question

In ABC if angle A = x, angle B = y and angle C = z such that x = 4y/3 and y 3z/8 then angle B is

Answer 1

Answer:

Angle B = 36°

Step-by-step explanation:

A+B+C = 180

x + y + z = 180

x = 4y/3; y = 3z/8 => z = 8y/3

//replace x and z in terms of y.

4y/3+y+8y/3 = 180

15y/3 = 180

5y = 180

y = 36°

Angle B = 36°
