C is the circumcenter of APQR.<br> PC=3x+7, RC=5x-15, & QC=51-X<br> x=[?]

amm1812

Answer:

x = 11

Step-by-step explanation:

C is the circumcenter of $\triangle PQR$

$\implies PC=QC=RC$ (Radii of same circle)

$\implies RC=QC$

$\implies 5x-15=51-x$

$\implies 5x +x=51+15$

$\implies 6x =66$

$\implies \: x = \frac{66}{6} \\ \\ \implies \: \huge \: \red{x = 11}$

Fill in the other coordinate for the line 2x - 5y = 11: (4, )

enot [183]

2x - 5y = 11. (4, a). x = 4, y = a

Substituting into 2x - 5y = 11

2(4) - 5(a) = 11

8 - 5a = 11

-5a = 11 - 8

-5a = 3

a = 3/-5 = -3/5 =- 0.6

Other coordinate = -3/5 = -0.6
