Question

one angles of an lsoscles is 120 ? a) draw a rough figure and find sum of other two angles . b) Find the other the two the angles .​

Answer 1

Step-by-step explanation:

let the angles be x,

as an isosceles triangle has two equal angles

so

sum of the sides= 180

120+x+x=180

120+2x=180

2x=180-120

2x=60

x=30

so both angles are 30,30
