Since both C & D are parallel, angle 2 is a corresponding angle to the angle of 108 degrees, so angle 2 is also 108 degrees
Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
<em>Looks like 3/4 of a full circle</em>
<em>The area of a circle is calculated with the formula: </em>
<em>Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.</em>
<em>The radius is given as 3 inches</em>
Area = 
cubic inches = 28.3 cubic inches
------------------------
<em>Perimeter is calculated with </em>
<em>.</em>
<em>But this is 3/4 of a circle with an additional two 3-inch sides</em>
Perimeter = 
+ 2(3) = 14.1 + 6 = 20.1 inches
Answer:
angle C = 64 degrees
Step-by-step explanation:
sin C = cos B
angle C = 10x+4
angle B = 4x+2
angle C + angle B = 90 degrees
10x+4 + 4x+2 = 90
simplify:
14x+6 = 90
14x = 84
x = 6
angle C = 64 degrees
Basically what you have to do is substitute the variables for the values
-4+-9+5= -8
-2-3= -5
2= 2
6-4+1= 3
-9(-2+-4--3)= 27
Answer:
121.5 cm^2.
Step-by-step explanation:
Each face has area 4.5^2 = 20.25 cm^2.
There are faces so the total surface area = 20.25 * 6.
