Answer:
8
Step-by-step explanation:
3 - (-5)
This can be rewitten to
3 + 5
Why?
2 negatives cancel each other out to make a positive, therefore:
3 + 5 = 8 or 3 - (-5) = 8
The opposite angles of an inscribe quadrilateral are supplementary.
angle P + angle R = 180
6x + 7 + 12x + 11 = 180
18x + 18 = 180
18x = 162
x = 9
Now we will substitute in the value of x to find angle P and R.
angle P = 6(9)+7 = 61
angle R = 12(9)+11 = 119
Now we will find the value of y.
angle Q + angle S = 180
10y + 7 + 3(3y + 7) = 180
10y + 7 + 9y + 21 = 180
19y + 28 = 180
19y = 152
y = 8
Now substitute in the value of y to find angle Q and S.
angle Q = 10(8)+7 = 87
angle S = 3(3*8+7) = 93
Hope this helps :)
Take it and divide it by 5, or you can multiply it by .2
PXrXt /100 is the formula
