1. which of the following could be
the measurements of two
complementary angles?

a. 7º and 830
b. 83° and 830
c. 97º and 83°
d. 117° and 83°

Step-by-step explanation:

I don't know if this helps, but none of the above.

first of all, complementary angles mean that the 2 (or more) angles add up to 90 degrees. so, if you were to combine the angles, you'll get an angle that's way larger than 90 degrees. (a and b won't work cause 830 isn't an angle)

P.S. but 83 degrees and 7 degrees would be complementary...

hope you at least know why i say none of the above

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you
