Devin started the work shown to solve for the unknown angle measures. 8x – 1 + 9x – 6 = 180 17x – 7 = 180 17x = 187 what are the measures of angles q and r?

Step-by-step explanation:

we have that

------> by supplementary angles

Substitute the values and solve for x

Find the value of angle R

Find the value of angle Q

The measure of angle Q and R can be obtained by supplementary angle. The supplementary angle is defined as the addition of two angle is .

The angle Q is and angle R is .

Given:

The equation for unknown angle is,

The supplementary angle is,

Compare the above equation.

Solve the given expression.

Calculate the Angle R.

Calculate the Angle Q.

Thus, the angle Q is and angle R is .

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
