1) The measures of the opposite angles of an inscribed quadrilateral are supplementary, add up to 180.

That means that angle ROP and angle RQP are supplementary.

We can add them and set them equal to 180 so that we can solve for x first.

∠ROP + RQP = 180
x + 17 + 6x - 5 = 180
7x + 12 = 180
7x = 168
x = 24

Now use the 24 for x and solve for the measure of angle ROP.

∠ROP = x + 17
∠ROP = 24 + 17
∠ROP = 41

The answer is A

2) The answer is A.

Hope this helps :)

The temperature at a state park for one day in June can be approximated by the function T(x) = 0.264x2 - 4.752x + 81 0 ≤ x ≤ 18

Lilit [14]

Answer:

60 °F

Step-by-step explanation:

The function can be put into vertex form:

T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms

Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.

T(x) = 0.264(x² -18x +81) +81 -0.264·81

T(x) = 0.264(x -9)² +59.616
