Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
Given:
In the given triangle,
With respect to y, Perpendicular = 10 cm and Base = 8 cm
To find the value of y.
Formula
By Trigonometric Ratio we get,

Now,
Putting the values of perpendicular and base we get,

or, 
or, 
Rounding off to the nearest tenth, we have;

Hence,
The value of y is 51.3°.
(4/7)^3=.1865
