The measure of an angle is 172.4°. What is the measure of its supplementary angle?

Step-by-step explanation:

in supplementary angle sum of two angle is always 180 degree.so,

let another angle be x

x+172.4=180

x=180-172.4

x=7.6

7.6

Step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
