Question

in triangleABC if angle A + angle B =180deegree and angleB + angleC = 130deegree find angleA ,B , C​

Answer 1

if angle A + angle B

this is impossible

Answer 2

Step-by-step explanation:

As we know sum of the angles of the triangle is 180°

A+B+C =180 -------------(1)

Given A + B =180

A= 180-B ------------(2)

Given B+C= 130

C= 130-B ------------(3)

Substitute 2 and 3 in 1

180-B+B+130-B=180

B = 130°

Put B in (2)

A = 180-130 = 50°

put B in (3)

C = 130- 130 = 0°

There is no scope for formation of a triangle with an angle 0° . Since you have given A+B = 180°, wouldn't be possible for a triangle. In any case the sum of three angles make 180 but not two angles make 180.

If you are really willing to find the angles then they are 50 , 130, 0
