Answer:

Step-by-step explanation:
The zeros of a function is where the function crosses the x-axis. The x-intercepts are the zeros of a function.

Let output equal to 0.

Set factors equal to 0.


The zeros of the function are
and
.
If you have never used a unit circle, I recommend making one.
R for the following degrees are
30*= 4((3^1/2)/2)^2
60*= 8(2^1/2)(2^1/2)^2
90*= (8((3^1/2)/2))/4
Hi there!
• Base, b = 8 units
• Altitude, a = 10 units
Area of Triangle =

× b × a =

× 8 × 10 = 40 units.
Hence,
Th' required area of triangle is 40 units
