The way the diagram looks when it is drawn is that you are going to need the sine function to solve for the side opposite which is CD.
Formula
Sin(A) = Sin(68 = opposite / hypotenuse Substitute values.
Solution
sin(68) = altitude (side opposite) / 20 multiply both sides by 20
20*sin(68) = 20* altitude / 20 substitute for sin(68)
20* 0.9272 = altitude
altitude = 18.5
Answer: 18.5 to the nearest tenth
Answer:
of oil.
Step-by-step explanation:
Firstly, you need to find the LCD (lowest common denominator), this can be done by factoring the denominators and knowing the multiples.
In this case, you can see that 2 is a factor of 8 so we can simply multiply so that the denominator is 8:
8 ÷ 2 = 4
Now the fractions can be added easily:
= of oil.
Hope this helps!
Answer:
if we are talking on a standard graph then the origin is 0 on the x axis and 0 on the y axis
Step-by-step explanation:
Mean = (12 + 13 + 14 + 9 + 7 + 8 + 15 + 10) / 8 = 88/8 = 11
Median = 7, 8, 9, 10, 12, 13, 14, 15 = 11 (between 10 and 12)
Mode = None because there are no numbers that occur more than once
