Answer:
8 hours
Step-by-step explanation:
You can solve this problem by inputting the values into an equation. Here is the equation below:
Lets solve for x. First you subtract 50 from 130.
1)
2)
Next, you divide 80 by 8 to get x by itself.
1)
2)
This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
Answer:
m∠MBC=m∠MCB by reason base angle theorem
Step-by-step explanation:
First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.
Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
Answer:
= 40
Step-by-step explanation:
so if you mean x = -8
Answer:
Identity is verified.
Step-by-step explanation:
We have to verify the identity
To prove any identity we always prove one side(either left hand side or right hand side) of the equation equal to the other side.
In this identity we take the left hand side first
(as we know cos(a+b) = cosa×cosb-sina×sinb)
= - sinx ( Right hand side)
Hence identity is proved.
