One angle of a triangle measures 10°. The other two angles are in a ratio of 2:15. What are the measures of those two angles?

Well the measurements of a triangle adds up to 180.

So we know that one angle is 10degree.

So we can do 180-10 and that gets us 170.

They mention that they are in a ration of 2:15.

We can add that up to get 17. And divide 170 by 17. This gets us 10.

So 15*10 and 2*10 would get us the measurements of the two angles.

15:2

150degree:20degree

Step-by-step explanation:

sum of other two angles=180-10=170°

sum of ratios=2+15=17

one angle = (2/17) * 170=20°

second angle = (15/17) * 170=150°
