A triangle has an angel of 25 degrees. The other two angles are in a ratio of 15:16. What are the measures of those two angles?

All triangle angles sum to 180 degrees.

A) 25 + x + y = 180 which equals

A) x + y = 155

B) 15x = 16y

B) x = 16y / 15

Then substituting this into A)

A) (16y / 15) + y = 155

Multiplying both sides by 15

A) 16y + 15y = 2,325

A) 31y = 2,325

y = 75

Putting this into equation A)

A) 25 + x + y = 180

A) 25 + x + 75 = 180

A) 100 + x = 180

A) x = 80
