Question

An angle of 78 degrees is supplement of another angle. what is the measure of this angle?​

Answer 1

we know that supplementary of two angles =180

Let another angle be X

78 + X =180

X = 180-78

X = 102 °

therefore supplementary of 78 is 102°

Hope it helps you ...

Answer 2

Given,

An angle of 78° is a supplement of another angle.

To find,

The measure of another angle.

Solution,

The measure of another angle will be 102°.

We can easily solve this problem by following the given steps.

According to the question,

An angle of 78° is a supplement of another angle.

We know that the sum of the supplementary angles is 180° and the sum of complementary angles is 90°.

Let's take another angle to be x.

(78+x)° = 180°

x = (180-78)°

x = 102°

Hence, the measure of another angle is 102°.
