Question

in a triangle ABC if angle a - angle b = 33 degree and angle b - angle C =18 degree then angle b =​

Answer 1

Answer:

A = 88°

B = 55°

C = 37°

Step-by-step explanation:

A - B = 33

B = A - 33

-----------

B - C = 18

B = C + 18

-----------

A - 33 = C + 18

A = C + 51

------------

A + B + C = 180

C + 51 + C + 18 + C = 180

3C = 111

C = 37°

----------

A = C + 51 = 88°

B = C + 18 = 55°
