Answer:
Step-by-step explanation:
7*(7 + x+1) = 6*(x + 5 + 6) {Intersecting secant theorem}
7 *(x + 8) = 6*(x + 11)
Distributive property,
7x + 56 = 6x + 66
Subtract 56 from both sides
7x = 6x + 66 - 56
7x = 6x + 10
Subtract 6x from both sides
7x - 6x = 10
x = 10
X=79/6 - 5y-6
Y=79/5 -6x/5
The answer is reduction. This can be found by the size and number differences in the two quadrilaterals.
-10.6, and 9/10, are the constants
