Answer:
Step-by-step explanation:
To better understand the question we need to properly format the expression
as we can see we have three brackets, we can proceed by first opening the first two brackets, we have.
we then continue by collecting like terms
we then solve for the remaining two brackets
we then continue by collecting like terms
from the two brackets we obtained each, we now have to multiply both terms together and solve we have
collecting and summing all like terms we have
It's kinda hard to see the top 2 so I wont answer them only because I can't see it clear enough and I don't want to give the wrong answer because i thought it said something else but i can help with #10, anyway here's what I got it might not be fully right because I'm learning this same thing, but I'm pretty good with it.
#10. Since a triangle has a total measure of 180 degrees, you have to figure out how to get each angle to equal 180 when all 3 are added together, so here's how you solve it:
Step 1- Figure out what X represents in this question. Let's start with angle W. They already give you part of the equation, which is W= x +6. So now the next angle is X which the equation is X= 5x-12. The 3rd angle is Y= 7x-48.
Step 2- Add/ subtract the equation for each angle, and write what you got for your answer after each equation.
Step 3- After you have done step 2, try to mess around with each angle (multiply,subtract, etc.) until you got the angles to where they equal to 180 when added together.
Step 4- Write down the value of X in the blank that helped you solve the question. Do the same thing for the 3 angles.
I'm not giving the answer, but do the steps and you will be able to get it. It also helps you so you can do these on ur own.
I don't know if these are the steps u were taught, but this is how my math teacher taught me and the class.
Hope this helps, tell me if it got u the right answer or not!! :-)
This is the expression written with only sinx and cosx.
