Answer:Area)=12x(Base)x(Height)Step-by-step explanation:
*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆
Answer: 116.12
Explanation:
13 x 7 = 91
13 - 5 = 8
8 / 2 = 4
3.14(4)^2 = 50.24
50.24 / 2 = 25.12
91 + 25.12 = 116.12

Answer:
the answer is to use the formula lxwxh or length x width x height
They intersect at a right angle
Sin angle that equals the 1/2 value is the 30 degree on the 1st Quadrant.
The angle of 30 degree on the 3rd Quadrant is equivalent to (formula and circle in the 1st photo) 180 + 30 = 210°.
So theta = 210° (3rd Quadrant) = 30° (1st Quadrant).

Now just transfer the cos 30° to the 3rd Quadrant and the signal will be negative (as shown in the 2nd photo attached).
