The degree measure of angle A is 140 °. The degree measure of angle B is 65% of the degree measure of angle A and 70% of the angle C. Find the degree measures of angles B and C.
1. Let 140⁰ be 100%.
2. Let’s find how many degrees fall on 1%.
140/100 = 1.4⁰ falls on 1%.
3. Find the degree measure of the angle B by multiplying the number of percent by the number of degrees per 1%.
65 * 1.4 = 91⁰ degree measure of angle B.
4. Find how many degrees fall on 1% of the angle B.
91/70 = 1.3⁰ accounts for 1%.
5. Find the degree measure of the angle C. multiplying the number of percent 100% by the number of degrees per 1%.
1.3 * 100 = 130⁰ degree measure of the angle C.
Answer: 91⁰; 130⁰.
