Question

Solve for x. Then, classify the triangle by its sides and angles.

Answer 1

x = 20

Explanation:

The sum of interior angles in a triangle is equal to 180° so we can write the following equation:

2x + 3x + 4x = 180 add like terms

9x = 180 divide bot sides by 9

x = 20

all angles have measures under 90° so it's an acute triangle and if angle measure are different from each oter e all side lengths would have different lengths so it's also a scalene triangle.
