Question

in a triangle ab c if a-b=33° and b-c =18° the angle b=?

no wrong ans otherwise I will report the answer​

Answer 1

THE GIVEN. A-B = 33 -------- (¡)

B - C = 18 -------(¡¡)

we know that

A+B+C = 180

A = 33+ B

B-18=C

$a + b + c = 180 \\ 33 + b + b + b - 18 = 180 \\ 3b + 15 = 180 \\ 3b = 180 - 15 \\ 3b = 165 \\ b = \frac{165}{3} \\ b = 55$

B=55°
