Front

If ΔNML∼ΔSRL, solve for x.

Back

x = 5

Front

The ratio of the measures of two supplementary angles is 3:6. Find the measure of the larger angle.

Back

The larger angle measures 120º.

Front

Solve for x: x = ?

Back

x = 3

Front

The ratio of the angle measures of a triangle is 2:7:9. What is the measure of the smallest angle?

Back

The smallest angle measures 20º.

Front

Back

x = 4

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180º.

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180º.

Front

Define the term 'ratio'.

Back

A ratio is a comparison of two quantities by division.

Front

What is the formula for finding the measure of an angle in a triangle given the ratios?

Back

If the ratios are a:b:c, then the angles can be found using the formula: angle = (ratio/total ratio) * 180º.

Front

How do you solve for x in a proportion?

Back

Cross-multiply and then solve for x.
