The right angle is divided into two corners so that one of the resulting corners is 80% of the right angle. Calculate the size of each corner.
Answer: the angles are 72 ° and 18 °.
A right angle is an angle that has a degree measure of 90 °.
It is known that the value of one of the angles is 80% of 90 °. To find the percentage of any value in another, you need to divide the original value by 100, thereby finding out how much 1% is, and then multiply the result by the desired number of percent:
90/100 * 80 = 72 °.
If a right angle is divided into 2 angles, one of which is 72 °, then the second angle will be:
90 – 72 = 18 °.
