Triangle Angle Word Problem 3

In this lesson, Julie Harland, your math gal, demonstrates how to solve word problems involving angles in a triangle. By defining variables, writing equations, and checking their answers, students learn how to find the measures of angles in different types of triangles, including isosceles and right triangles. With clear explanations and helpful tips, students can quickly master these types of problems and become more confident in their math skills.

• In a triangle, if one angle is 4 degrees more than the measure of the smallest angle, and the measure of the third angle is twice the measure of the smallest angle, what is the measure of each angle?
• How do you write and solve an equation to find the measures of angles in a triangle?
• If expressions for three angles in a triangle are x, x + 4, and 2x, what does x equal, and what is the measure of each angle in the triangle?
• What is an easy way to solve 4x + 4 = 180?
