Answer:
y = -1
Step-by-step explanation:
(y+1)/(x-8) = (-1+1)/(-2-8)
(y+1)/(x-8) = 0
y+1 =0
y= -1
2x+7=x+3
2x+7=3
-×
x+7=3
-7 -7
x=-4
We know that
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
(2x-5)+(4x-1)+30=180
6x+24=180
6x=156
x=26°
the answer is
x=26°
Given:
A prism with right triangular base.
Base of triangle = 6 ft
Height of triangle = 8 ft
Height of prism = 7
To find:
The volume of the given prism.
Solution:
The volume of prism is:
...(i)
Where, B is the base area and h is the height of the prism.
In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:
Substituting in (i), we get
Therefore, the volume of the prism is 168 cubic ft.
