Angle ABC is 70 degrees. The degree standard of the CBD angle is 80% of the degree standard of the ABC angle. find the degree measure of the angle ABC.
70 degrees is the degree measure of the ABC angle.
Let’s conventionally denote the degree measure of the CBD angle – a.
The degree measure of the CBD angle is 80% of the ABC angle.
Then the following proportion is obtained:
70 degrees – 100%.
and degrees – 80%.
70 * 80 = a * 100.
5600 = a * 100.
a = 5600/100.
a = 56.
Solution: The degree measure of the CBD angle is 56 degrees.
