Answer:
48°
Step-by-step explanation:
we know that opposite angle of parallelogram is equal
so,
angel C is equal to opposite angle H
H = 48
angle C = 48°
angle R = 132°
angle H = 48° (opposite of angle C)
angle S = 132°(opposite of angle R)

Answer:
(1) Parallelogram A parallelogram is a quadrilateral with two
sets of parallel sides. The opposite or facing sides of a
parallelogram are of equal length, and the opposite angles of a
(2) Square
A square is a regular quadrilateral. This means that is has four
equal sides and four equal angles.
(3) Rhombus A rhombus is a quadrilateral whose four sides all have the same
length. Opposite angles of a rhombus have equal measure. The two
diagonals of a rhombus are perpendicular.
(4) Rectangle
A rectangle normally refers to a quadrilateral with four right
angles.
Parallelogram
Step-by-step explanation:
1. D bc switch the 1/3 into 3/1, then 4 time 3/1 = 12. Basically 4 times 3 =12
2. D
Answer:
.6601
Step-by-step explanation:
to find u, which we assume is an angle of course, we can take arctan of both sides. so arctan(-7.721) = -1.4420. this angle is in quadrant 4, but it is not in the range. In this instance you just go around the circle again, or add 2pi, which gets us 4.8412. You can check and you get the same answer if you take the tangent of either.
So now we have a number in the appropriate range in the appropriate quadrant. That means we have the correct angle. The question asks what is sine of that angle cut in half. so sin(4.8412/2), which gets you your answer. let em know if something didn't make sense.
This is how i worked it out.
Good Luck
