The measure of an angle is nine times the measure of its complementary angle. What is the measure of each angle?

9, 81

Step-by-step explanation:

Complementary angles add to 90

Let x = first angle

The other angle is 9x

x+9x = 90

10x = 90

Divide each side by 10

10x/10 =90/10

x = 9

The first angle is 9

The second angle is 9*9 =81

9  ; 81

Step-by-step explanation:

one angle = x

It's complementary angle = 9*x = 9x

Sum of complementary angles = 90

x + 9x = 90

10x = 90

x = 90/10

x = 9

It's complementary angle = 9x = 9*9 = 81

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
