Answer:
A. 
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] sinθ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
sin 30°
<u>Step 2: Solve</u>
Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.
Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.
Substituting it into sin, we have:
sin 30° = 1/2 = 0.5
∴ our answer is A.

Answer:
115 square units
Step-by-step explanation:
The area of a parallelogram is the product of base length and height. The height is the perpendicular distance between the bases.
A = bh
A = (23)(5) = 115 . . . . square units
Answer:
equation for perpendicular bisector passing through CB is;
y=⁴/³– 5/30
Answer:
l =10 units, 9.7 units, 5.5 units
Step-by-step explanation:
Area = length x breadth
Area of a square = l^2
100= l^2
√100 =√l^2
l=10 units
95=l^2
√95 = √l^2
l= 9.7 units
30=l^2
√30=√l^2
l= 5.5 units
