To solve for the last side of the triangle, use the Pythagorean Theorem:
(8)^2 + x^2 = (9)^2
x = sqrt of 17
However, this is a NEGATIVE sqrt 17 because the terminal side is in quadrant 4, meaning that this side is under the X-axis and therefore negative.
Now that you know the side opposite of u in the triangle, do opposite/hypotenuse.
sin u = -(sqrt 17)/9
Answer:
The steady state solution of the system is calculated in the diagram below:
You have to solve for F so you need to get it by itself which means it would look like:
9/5C+32=F
Then you plug in 33 for C and solve. When you round to the nearest whole number, you get D. 91
Solve each system by substitution. Check your solution. Writing How do you know that substitution gives the answer to a system of equations? ... You Would solve the second equationfor y and then substitute back into the first equation.
