Step-by-step explanation:
A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.
In the unit circle below, we can see that the line touches the unit circle at point
, therefore to find the tangent of theta, we use the formula:

Answer:
The new perimeter would be 36cm.
Step-by-step explanation:
The perimeter would change because you add 3 to two sides, because the perimeter originally was 5+5+10+10. Now, it's (5+3)+(5+3)+10+10. Which is 36.
Answer:
1224 cm^3
Step-by-step explanation:
volume = bottom area x height
102x12=1224
Answer:
20
Step-by-step explanation:
Evaluate is just simplifying so
4 times 3 is 12 times the negative makes it -12
then add 32 and -12 together
and you get 20
Answer:
