Answer:
8.6 cm
Step-by-step explanation:
We notice the hypotenuse is given, and the desired length is of the side opposite the given angle.
The mnemonic SOH CAH TOA reminds you of the relevant relationship:
Sin = Opposite/Hypotenuse
sin(35°) = x/(15 cm) . . . . . . fill in the given information
We can multiply by 15 cm to find the value of x.
x = (15 cm)sin(35°)
x ≈ 8.6
_____
For those inclined to copy this answer to a different question, we suggest ...
y = (15 cm)cos(35°) ≈ 12.3 cm
Vertex: (5,0)
Focus: (5,1/4)
Axis of symmetry: x=5
Directrix: y= -1/4
= 2x^3 +8x^2 +16x - x^2 -4x -8
= 2x^3 +7x^2 +12x -8
-24+m=-47
First, you add 24 to -47. Then you find that m=-23. To check your work, plug -23 in the equation for m, and solve.
