What is the measure of {CED and {ACD?

pogonyaev

Answer:

Part a) $m$

Part b) $m$

Step-by-step explanation:

step 1

Find the measure of angle ACB

we know that

The sum of the measures of interior angle of a triangle must be equal to $180\°$

In the triangle ABC

$m$

step 2

Find the measure of angle ACD

we know that

$m$ -------> by supplementary angles

we have

$m$

substitute

$m$

step 3

Find the measure of angle CED

we know that

m<DCE=m<ACB ------> by vertical angles

$m$

Remember that

The sum of the measures of interior angle of a triangle must be equal to $180\°$

In the triangle CDE

$56\°+60\°+m$

$116\°+m$

$m$

Find the equation of the circle with center at (-1, 3) and radius of 4. a. (x - 1)2 + (y + 3)2 - 4 c. (x - 1)2 + (y + 3)2 = 16 b

Pie

$\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{-1}{ h},\stackrel{3}{ k})\qquad \qquad radius=\stackrel{4}{ r} \\\\\\\ [x-(-1)]^2+[y-3]^2=4^2\implies (x+1)^2+(y-3)^2=16$

PLEASE HELP QUICKLY!!!<br><br> x^2 + (x+9)^2 = 45^2

andreev551 [17]

Step-by-step explanation:

x^2+(x+9)^2=90

x^2+(x+9)^2-90=0

x^2+x^2+9^2+2*x*9-90=0

x^2+x^2+81+18x-90=0

2x^2+18x-9=0
