Which of the following pair of angles is the complementary angle? 25 and 65 31 and 71 60 and 40 145 and 35

Step-by-step explanation:

If the sum of a pair of angles is 90, then they are complementary angles.

25 + 65 = 90

So, 25 and 65 are complementary angles

25 and 65

Step-by-step explanation:

complementary angle= either of two angles whose sum is 90°

25 and 65, sum = 90°

31 and 71, sum = 102°

60 and 40, sum = 100°

145 and 35, sum = 180°

14.4 miles

Step-by-step explanation:

To answer this question you first need to find out what Amanda can jog in 1 hour. I can do this by dividing by 5, since the question tells me that she jogs 18 miles in 5 hours. So, I do 18 divided by 5, which gives me 3.6. I now know that in one hour, she can jog 3.6 miles.

The next step is to multiply by 4, because I want to know what she can do in 4 hours. So, I do 3.6 multiplied by 4, which gives me 14.4. I now know she can jog 14.4 miles in 4 hours, which is my final answer,
