BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
Answer:
<h3>-3</h3>
Step-by-step explanation:
For two parallel lines. their slope are equal
Find the slope of each of the lines
For line A;
m = 0 -y/0+1
mA = -y/1
For line B;
mB = 9 - 3/8 - 6
mB = 6/2
mB = 3
since their slope are equal hence mA = mB
-y/1 = 3
-y = 3
y = -3
Hence the value of y is -3
Answer:
40-19 = 21
Step-by-step explanation:
I think this is correct dear
Answer:


let us first take a look at the values of the trigonometric ratios given in the question so that we get quite clear about what is to be done.
here ,

now ,
we just have to plug in the values considering certain other things given in the question and we're done!
so let's start ~

hence , proved ~
hope helpful :D
The marginal product of the labor which joan can make a bottle 8 smoothies in an hour and when she is wokring with her friend they can make a total of 18 bottle of smoothies an hour. The formula is 18 / 2 = 9.9 is the marginal product of labor.So the answer is C. 9
