Just grab your calculator and multiply it by itself or use the 'square' function
Answer is 4040.233866
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 :)
Answer:
y = -5/6x-5
Step-by-step explanation:
because the slopes need to be the same for parallel lines
B=1.4
Is the answer.
This is just for more characters <span />
Y=4x+3 bc 3 means how far up the y axis you go. 4 determines how steep the slope is
