Question

In a triangle ΔABC if ∠A+∠B=108° and ∠B +∠C=130° find ∠A , ∠B , ∠C

Answer 1

Answer:

Step-by-step explanation:

A+B=108-----(1)

B+C=130------(2)

add (1) and

(2)

A+B+B+C=108+130

A+B+C+B=238

180+B=238 [since A+B+C=180]

B =238-180

B=58

substitute B =58 in (1) u will get A and

in(2) get C

A=50

C=72

B=58
