The sum of the measures of angle m and angle r is 180° .
· the measure of angle m is (5x+10°)
· the measure of angle r is 45°.

what is the value of x?

explain how to do it!

x =25

Step-by-step explanation:

<M + <R = 180

We know M = 5x+10  R = 45

Substituting these values in

5x+10 + 45 = 180

Combine like terms

5x+55 = 180

Subtract 55 from each side

5x+55-55 = 180 -55

5x = 125

Divide each side by 5

5x/5 = 125/5

x = 25

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
