Basically the -8 shows you the y value that the vertex has !! You can also use desmos to visualize
60° , 360° , 720° , and 300° hope i helped and have a great reast of the week and weekend
Answer:
r = 28.28
Step-by-step explanation:
you already gave the equation: sin45°= 20/r
you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:
r (sin45°) = 20
Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:
r = 28.28
P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)
