theta is in the fourth quadrant where the cosine is positive.
the third side in the triangle = sqrt (4 - 2) = sqrt2
So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)
tan theta = - sqrt2 / sqrt2 = -1
Yes because if yuo add 12 more your adding 12 more of students to make 24

When we speak of the word "perimeter" of a circle, we mean to say the circumference. Since we are only given a semicircle, the perimeter would be,
perimeter = (pi)(radius) + diameter
Substituting the known values,
perimeter = (3.14)(6 cm) + 12 cm
The value of the perimeter is,
perimeter = 30.84 cm
Answer:
2 units^2
Step-by-step explanation:
The area of a triangle is given by the formula
A = 1/2 bh where b is the length of the base and h is the height
b = 2 and h =2
A = 1/2 (2) * (2)
A = 1/2*4
A = 2 units^2
