Without a diagram, one must make certain assumptions about this problem. If and only if these three angles are the interior angles of a triangle, then their sum must be 180 degrees, so that 18x+12 + 6y + 3x+4y = 180. Unfortunately, this is a single equation in 2 unknowns. Thus, we cannot solve for an explicit value for either x or y.
If there was a diagram, please share it; otherwise, describe the triangle in words as best you can.
You would begin by choosing which trigonometric function to use.
In this case, you would use sine.
Sine is opposite over hypotenuse.
Opposite of the 35 degree angle is 18, and you want to find the hypotenuse which is x.
sin(35) =
(multiply x to both sides)
x sin(35) = 18 (divide sin(35) to both sides)
x = 31.38204...
So, therefore
x = 31.38. I don't know what decimal point you're supposed to round to, so I'm gonna guess the hundredths place. :)
Answer:
a) f(n) = 11 + f(n - 1)
Step-by-step explanation:
f(2) = 11 + 4 = 15
f(3) = 11 + 15 = 26
f(4) = 11 + 26 = 37
f(5) = 11 + 37 = 48
I hope this helps you
7a/7=49/7
a=7
The first two should be odd functions and the last one is even
