Answer:
x ≈ 4
Step-by-step explanation:
We use tan∅ to solve this:
tan30° = x/7
7(tan30°) = x
x = 4.04145
Remember that tangent is opposite over adjacent.
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 :)
13/16 divided by 7/8 is 13/14
13/14(7/8)= 91/112= 13/16
Answer:
Step-by-step explanation:
To find answer,
We multiply 2 hours by the decrease, which is 3 degrees.
2*3=6 degrees
Now this means it will decrease 6 degrees in 2 hours, and starting from the start we do
0-6= -6 degrees in 2 hours
For five hours, we do
5*3=15
Now do the same
0-15= -15 degrees
