Sine rule
a/Sin(A) = b/Sin(B) = c/Sin(C)
b
C / |
a / _| A
B c
We know that a = 70 degrees and A = 25 foot
So 70/Sin(25) = Something
We also know we want C, and that c = 90 degrees
So 70/Sin(25) = 90/Sin(C)
Then you have to rearrange the equations. Start with Multiply all by Sin(C)
So [Sin(C)][70/Sin(25)] = 90
Then divide everything by 70/Sin(25)
So Sin(C) = 90/[70/Sin(25)]
Now you want to isolate C, so Sin-1 everthing
So C = Sin-1{90/[70/Sin(25)]}
So C = 32.91309534
To the nearest tenth, 32.9ft
Hope that helps :)
Less than because if you subtract 11, 138 minus 9,405 you get the answer you get 1,733 and that is less than 2,000
Answer:
8 inches
Step-by-step explanation:
Nacho cheese
v= Pi×radius×2×height
v = 3.14×8×2×4 = 200.96
jalapeño
3.14×4×2=25.12
200.96÷25.12=8
the height is 8
to check your work you can do
(multiply by 8 and see if it equals 200.96)
3.14×4×2×8 = 200.96
since the volume is the same as the volume for nacho cheese we can say that 8 inches for height is correct
If you have your points (3,4) (1,2) x=3 and 1 and y=4 and 2 so find a point on the x or y line and go up and over till your line crosses another point and that will give you your slope
