Answer:
91.30 minutes
Step-by-step explanation:
Assuming that when you start charging the phone it had 0% charge, what you should do is a rule of three.
That is, yes in 21 minutes I charge 23%, how long will it take to charge 100%.
charge time charge percentage.
21 minutes 23%
x minutes 100%
Then it would be:
x = 100 * 21/23 = 91.30
So you would have to wait 91.30 minutes to wait for the full charge.

Answer:
Therefore the measures of the angles are 22.5° and 67.5°.
Step-by-step explanation:
Complementary Angles:
Two angles are Complementary when they add up to 90 degrees.
Example 40° and 50° are Complementary Angles.
If 'x' and 'y' are Complementary Angles the we have

Here,
Let the common multiple be 'x '
Then the the Complementary Angles will be 'x' and '3x'.
....property of Complementary Angles.
Solving the equation we get

Substituting 'x' values we get
x= 22.5°
3x = 3 × 22.5 = 67.5°
Therefore the measures of the angles are 22.5° and 67.5°.
