Finding Angle Measures Using Algebra

Use an algebraic equation to find the measure of the two angles.

• x = 90-16 ; 16°and 74°

• x + x - 16 = 180; 98 °and 82°

• 2x - 16 = 90; 53° and 37°

• x = x -16; 8° and 16°

Use an algebraic equation to find the measures of both angles

• x = 3x - 20; 10° and 10°

• 4x - 20 = 90; 27.5° and 62.5°

• 4x - 20 = 180; 50° and 130°

• 4x - 20 = 180; 150° and 30°

What equation would you use to find the value of x?

• 2x-6=7x+4

• 2x-6+7x+4=90

• 2x-6+7x+4=180

• 2x-6+7x+4=360

Solve for x.

• 74

• 53

• 37

• 13

Write and solve an equation to solve for x

• 3x - 1 + x + 5 = 90 and x = 21.5

• 3x - 1 + x + 5 = 180 and x = 44

• 3x - 1 = x + 5 and x = 3

Write and solve an equation to solve for x

• 2x + 25 + 3x = 90 and x = 13

• 2x + 25 + 3x = 180 and x = 31

• 2x + 25 + 3x = 180 and x = 41

• 2x + 25 = 3x and x = 25
