As and CD meet at point E. What is LAEC?
LAED and 2DES are supplementary angles
17
+0-32) - 180
3x + 15 = 180
3x = 165
x=55
LDES and ZAEC are vertical angles
LAEC = m_DES
= x+321
= (55 + 32)
=870
Som_AEC = 87
Look at the figure in the Example.
2. What is m_CEB? Show your work
SOLUTION
Describe how to find m_CEB another way.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

i dont know men

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
