Answer: x = 23

Step-by-step Step-by-step explanation:

The sum of any triangle's angles will add up to 180°. Since we already have a known angle, 65°, we can subtract that from 180°.

180° - 65° = 115°

Now we add the unknown angles (x) together:

4x + x = 5x

Lastly, we divide 115 by 5 to find x.

115/5 = 23

x = 23
