Answer:
<h2>288 ft³</h2>
Step-by-step explanation:
The formula of a volume of a prism:
where
<em>B</em><em> - area of a base</em>
<em>H</em><em> - height of a prism</em>
<em />
In the base we have the right treiangle. The formula of an area of a right triangle is:
where
<em>a, b</em><em> - are legs</em>
We have
Substitute:
Calculate the volume.
Substitute
A. x = -6
6-x-x = 18
6-2x =18
-2x = 12
x = -6
Can you use a calculator? If yes, then isolate 7) cot 8) tan 2 theta, etc. Then, input the inverse of that trig into the calculator.
Ex. #7 cot theta= -6/5
Then, input arccot (-6/5) (aka inverse cot (-6/5)) into your calculator.
Answer:
The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles. The adjacent angles are the angles which have a common vertex.
