The area of rectangle:
11 ft · 6 ft = 66 ft²
The area of triangle:
6 ft · 4 ft/2 = 6 ft · 2 ft = 12 ft²
The area of the shaded region:
66 ft² - 12 ft² = 54 ft²
Answer:
8.75
Step-by-step explanation:
The length of side b is 7.61 m.
Here's how the length was calculated:
Let:
length of side a = 12 centimeters
B = 36 degrees
C = 75 degrees
In order to solve an AAS triangle, use the three angles, add to 180 degrees to find the other angle, then, use The Law of Sines to find each of the other two sides.
A = 180 - (36 + 75) = 69 degrees
by using the law of sines:
a / sin A = b / sin B = c/ sin C
we will substitute the given values:
12 / sin (69) = b / sin (36)
b = unknown
12 / 0.93 = b / 0.59
12.9 = b / 0.59
b = 12.9 * 0.59
b =7.61 cm (length of side b)
Answer:
c = 3.4. I hope this is the answer:)
