Answer 1

Answer:

first you have to know which triangle it is

if its right angle triangle then

you have to do this 1/2×b×h

if it is isosceles triangle then

180 angle

Answer 2

Step-by-step explanation:

a+b+c=180

when one angle is given

let us take a=20

20+b+c=180

now, consider b=c

20+b+b=180

2b=180-20

2b=160

b=160/2

b=80

since b=c

c=80
