To start off with, the probability to draw the short straw is 1/9 and each time someone picks the long straw the denominator (the 9) decreases by one which means that the odds of someone picking it get higher.
The sum of the measures of two complementary angles is 90°. To put it another way, m∠P + m∠Q = 90°.
So, we can substitute the given values of the angles into this equation.
Then, to find m∠Q, we plug in 12 for x for the original expression of Q to get
.
I think the answer is y=2x
1/2(x+7). Hopefully that helped
