Question

Answer 1

If you're trying to find the missing angle in a triangle, you use the fact that the sum of the angles in a triangle is always 180 degrees.

You already have two angles given:
- The first angle is 15 degrees.
- The second angle is 85 degrees.

To find the third angle, you would add the two given angles together and then subtract that sum from 180 degrees.

First, let's add the given angles together:
15 degrees + 85 degrees = 100 degrees

Now, subtract this sum from 180 degrees to find the missing angle:
180 degrees - 100 degrees = 80 degrees

So, the missing angle measures 80 degrees.
