Question

in ∆ABC, angle a+angle b=180,angle b+angle c=130find angle a, angle
and angle c​

Answer 1

Step-by-step explanation:

In any triangle, the sum of all 3 angles is 180° . So,

angleA+angleB+angleC = 180°

108°+angle C= 180° (since angleA+angleB=108°).

angle C= 180°- 108°= 72°

angleA+ 130°=180°(since angleB+angleC=130°).

angle A= 180°- 130°= 50°

angle B= 180°-(72°+50°)= 58°

Answer 2

Answer:

In any triangle, the sum of all 3 angles is 180° . So,

angleA+angleB+angleC = 180°

108°+angle C= 180° (since angleA+angleB=108°).

angle C= 180°- 108°= 72°

angleA+ 130°=180°(since angleB+angleC=130°).

angle A= 180°- 130°= 50°

angle B= 180°-(72°+50°)= 58°
