Question

the angles are supplementry and the larger is 20० less than 3 times the small​

Answer 1

Answer:

)If angles are complementary then their sum should be 90 °

.

As per the given condition if smaller angle is X then the larger angle should be X+40 °

,

Now,

X+X+40 °

=90 °

2X=50 °

∘

X=25 °

∘

Hence, smaller angle is 25 °

∘

and larger angle is 65 °

∘

Answer 2

$\huge \sf \colorbox{grey}{solution} :$

x +( 3x-20)=180°

x + 3x-20=180°

4x-20=180°

4x= 200

x= 50

3x - 20 = (3×50-20)=150-20=130.

thus,

the smaller angle is 50° and larger angle is 130°.
