Which point lies on the circle represented by the equation (x+5) + (y-9) = 8
olga_2 [115]

Answer:

(-5,9+√8)

Step-by-step explanation:

There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.

the general equation of a circle is:

(x-h)^2+(y-k)^2=r^2

with center at (h,k)

you have the following equation:

(x+5)^2+(y-9)^2=8\\\\h=-5\\\\k=9\\\\r=\sqrt{8}

Then, the center is (-5,9)

if you sum the value of the radius in one of the fourth directions (up, down, left, right), for example upward you have

(-5,9+r)=(-5,9+\sqrt{8})

Then, one point that lies in the circle is (-5,9+√8)

If AJKL = ARST, which congruences are true by CPCTC? Check all that apply.
evablogger [386]

Based on the CPCTC theorem, the congruences that are true about the given triangles are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS

<h3>What is the CPCTC Theorem?</h3>

According to the CPCTC theorem states that if two triangles are congruent to each other, then, all their corresponding parts will be congruent to each other.

Given that triangles JKL and RST are congruent to each other, therefore:

∠J ≅ ∠R

∠K ≅ ∠S

∠L ≅ ∠T

JK ≅ RS

KL ≅ ST

JL ≅ RT

Therefore, the congruences that would be true by CPCTC are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS
