In a triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is 70° more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180° to find the measure of each angle.
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
In a

more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is
to find the measure of each angle.
