Question

in triangle ABC, if angle A =80 degrees, angle B = 70 degrees, then identify the longest and the shortest side

Answer 1

Answer:

let c be x

80+70+x=180

150+x=180

x=180-150

x=30

A = 80

B = 70

C = 30

SO, the largest side is A

and shortest side is C

Answer 2

Answer:

sum of all angles of triangle is 180.

80+70+C=180

C=30

Longest side=BC

Shortest side=AB
