Question

The interior angles of a triangle are aº bº and 20°. If the difference between a and bis 40", then find's
and 'b.​

Answer 1

Answer:

Let b be x

and a be x+40°

20°+x+40°+x=180 °

2x+60=180°

x= 60°

Answer 2

Answer:

A=40

B=120

Step-by-step explanation:

USING ANGLE SUM PROPERTY

A+B+20=180

A+B=180-20

AB=160

LET AB BE X

X=160/2

=80

BUT DIFFERENCE OF A AND B IS 40 SO,

A-40=80-40=40

B+40=80+40=120
