∠5 is a supplement of ∠6, and m∠5=78°. Find m∠6.

Step-by-step explanation:

Given that:

is a supplement of .

m = 78°

To find:

m = ?

Solution:

First of all, let us learn about the concept of an angle being a supplement of the other angle.

is known as supplement of , if sum of the two angles is equal to 180°.

.

For example, angle made on one side by a line intersecting the other line are supplement of each other.

Here, we are given that is a supplement of .

In other words:

Putting value of :

So, the answer is:

f(x) = y

f(-3) = -5
