Final answer:

The two angles in the triangle are 30° and 65°.


Step-by-step explanation:

Let the two angles in the ratio be 6x and 13x. The sum of the three angles in a triangle is always 180°. Therefore, we can set up the equation: 85 + 6x + 13x = 180.

Simplifying the equation, we get 19x + 85 = 180.

Subtracting 85 from both sides, we have 19x = 95.

Dividing both sides by 19, we find that x = 5.

Therefore, the two angles are 6x = 6(5) = 30° and 13x = 13(5) = 65°.
