Question

The measure of the supplement of 80° is
a) 10
b) 100°
c) 90°
d) 180
​

Answer 1

Answer :

$\sf\pink{Given}$

• measure of one angle is 80°

$\sf\pink{To\:find}$

• supplement of 80°

Explanation :

• let the supplement be "x"

Therefore as supplementary angles add up to 180°

$\longrightarrow\bf{ x + 80 = 180°}$

$\longrightarrow\bf{ x = 180° - 80°}$

$\longrightarrow\bf{ x = 100°}$

• Therefore the measure of the supplement of 80° is 100°

Answer 2

Answer:

${ \huge{ \red{ \sf{Solution:}}}}$

The measure of the supplement of 80° is 100

If the sum of two angles is equal to 180° . Then those angles are called as supplementary angles.

From question, one angle is 80°

Let us take it's supplement as x

$: { \sf{ \implies{ x + 80 = 180}}} \\ \\ : { \sf{ \implies{x = 180 - 80}}} \\ \\ : { \sf{ \implies{ x = 100}}}$

Therefore,

• The supplement angle of 80 is 100°

${ \therefore{ \sf{ \underline{ \pink{Option \: B \: is \: your \: answer}}}}}$
