Question

Find x and y -- if your answer is not a whole number, round to the tenths!

X=______
Y=_______

Answer 1

x ≈ 10.6

y = 15

Explanation:

The opposite angles in an inscribed quadrilateral are supplementary.

Therefore:

(4y+14) + (7y+1) = 180

=> 11y + 15 = 180

=> 11y = 165

=> y = 15

7x+1 + 105 = 180

=> 7x + 106 = 180

=> 7x = 74

=> x ≈ 10.6
