Question

In a angle ABC, Angle A is 25 more than angle B and angle C is less 10 than angle B what are the angles of the triangle

Answer 1

Angle A= angle B +25. 1
Angle C=angle B -10. 2
In triangle ABC
Angle A + angle B + angle C =180°
from 1 and 2
angle B + 25 + angle B + angle B -10=180°
3(angle B) +15=180°
3(angle B)=165°
angle B =55°

Answer 2

Answer:

Step-by-step explanation:

Angle A= angle B +25. 1

Angle C=angle B -10. 2

In triangle ABC

Angle A + angle B + angle C =180°

from 1 and 2

angle B + 25 + angle B + angle B -10=180°

3(angle B) +15=180°

3(angle B)=165°

angle B =55°
