I HOPE THIS HELP YOU TO UNDERSTAND

Answer 2

Answer:

16° and 80°

Step-by-step explanation:

Given one angle is 84°.

The other two angles are in the ratio 1:5

So, the other two angles are x° and 5x° for some number x.

Angle sum property tells us that the sum of all angles of a triangle is equal to 180°. So,

84 + x + 5x = 180

⇒6x = 180 - 84

⇒6x = 96

⇒x = 16

As we took the other two angles to be x° and 5x°, their measure is 16° and 80°.
