Question

find
in
the
following figure

​

Answer 1

Answer:

125°

Step-by-step explanation:

A traingle has 180°

one angle is 25°

another angle is 30°

sum of the angles = 180

A+B+C = 180°

25+30+C = 180

55+C = 180

C = 180 - 55

.C = 125°

Answer 2

Answer:

In triangle ABC.

angle A = 25°

anhle B = x

angle C =30°

so by angle sum property

sum of all angles = 180°

angle A + angle B + angle C = 180°

25° + 30° + x = 180°

55° + x = 180°

x = 180° - 55°

x = 125°

so angle B = x = 125°
