The ratio of the interior angle measures of a triangle is 2: 3: 5. what are the angle measures?

The angles are 36° , 54° and 90°

Step-by-step explanation:

Sum of interior angles of a polygon is given by 180(n - 2) where n is the number of sides.

Sum of interior angles of a triangle is 180(3 - 2) = 180°

The ratio of the interior angles is 2:3:5

So 2 + 3 + 5 should be equal to 180°

If 10 = 180°

Then 2 is 360°/10 = 36°

And 3 is 540°/10 = 54°

And 5 is 900°/10 = 90°

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
