Answer:
Step-by-step explanation:
Here is the complete question.
Line AB and CD intersect at E. If angle AEC = 4 x−40 and angle BED = x
+
50
, what is the number of degrees in AEC?
If lines AB and CD intersect at E
, then <AEC = <BED (oppositely directed angles)
Given
<AEC = 4 x−40
<BED = x
+
50
If <AEC = <BED, then;
4x-40 = x+50
4x-x = 50+40
3x = 90
x = 90/3
x = 30°
Also note that <AED + <AEC = 180
<AEC = 4x-40
<AEC = 4(30)-40
<AEC = 120-40
<AEC = 80
<AED +80 = 180
<AED = 180-80
<AED = 100
Hence the measure of angle AED is 100°
Answer:
Mariah
Step-by-step explanation:
If you divide 8/10 you get .8 move the decimal 2 times to the left and you get 80%.
Then you divide 36/40 and get .9 move the decimal 2 times to the left and you get 90%
Answer:
Step-by-step explanation:
You cannot add these because they are not like. IF you have a value for x, then the expression could be evaluated at the x value, but you can't add them.
Answer:
1728ft³
Step-by-step explanation:
Split the shape into the two rectangular prism that make it up
Volume of a rectangular prism=length*width*height
Small prism=10*12*3=360ft³
Big prism=19*12*6=1368ft³
Total=360ft³+1368ft³=1728ft³
