Answer:
<em>Angle C is equal to 30.</em>
Step-by-step explanation:
To find angle C, we have to find all the other angles first. They tells us the B ~= BAD ~= ADC. So, if we find ADC, we've found B and BAD as well. ADC is just 180 - 70 (the angle of ADE), which is 110. So, ADC, BAD, and B are equal to 110.
Remember, angles in a quadrilateral add up to 360. So, add all of the values of angles be have now and subtract from 360:
360 - (110 + 110 + 110)
360 - 330 = 30
Angle C should be equal to 30.
Hope this helped!
First you must add the same numbers together, for instance, you wouldn't add 4y with 4 you have to add it with another number that is just like it, for instance 4y and 9y they are the same, so you can add them. So let's get to the problem now:
5y(2y-3)=(2y-3)
5y*2y=10y
(10y-3)=(2y-3)
You can do nothing to the other side because there are no numbers, that are the same.
Answer:
-1
Step-by-step explanation:
Just substitute your variable in:
(2)(3)-7
Simplify:
2*3=6
6-7=-1
-1 is your answer.
