Question

Angles A and B are supplementary. Angle A has a measure of 80°. What is the measure of angle B?

The measure of angle B is °.

Answer 1

hola mate

here is ur answer

hope this helps ❤❤❤❤

sum of the two angles=180 degrees

angle A added to Angle B is equal to 180 degree .

80+Angle B=180

angle B=180-80=100 degrees

The measure of angle B is 100 °.

Answer 2

$<u><b><i>Question</i></b></u>$:

Angles A and B are supplementary. Angle A has a measure of 80°. What is the measure of angle B?

$<u><b><i>Answer</i></b></u>$:

The measure of angle B is 100°

$<u><b><i>Step-by-step solution</i></b></u>$:

As we know,

If two angles are supplementary,

then the sum of the angles is always 180°

Therefore,

<A +<B= 180°------(1)

Given that:

<A = 80°----------(2)

So,

From (1) and (2),

80° +<B =180°

=> <B = 180°- 80° =100°
