The complement of angle M is 10 degrees. What is the measure, in degrees, of angle M?

Complementary angles add up to 90 degrees.

Let x = complement of angle M is 10 degrees.

We want to solve x + M = 90.

Let's solve for M.

10 + M = 90

M = 90 - 10

M = 80.

The measure of angle M is 80 degrees.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
