Answer:
either 3 1/2 or 7/2
Step-by-step explanation:
4 is equal to 8/2
8/2 minus 1/2 is 7/2
7/2 can be simplified to be 3 1/2
the answer is 130 degrees, the 2 interior bottom angles are = to one another so 65 and 65, adding them up makes it 130, then 180 - 130 = 50, meaning the top interior angle is 50 degrees, then 180 - 50 is 130.
50 minus 5 equals 45 hope this helped give me brainliest plz
Answer:
Angle made by ramp with ground is ≈
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is
ft.
Height of Skateboard ramp is
ft.
From figure,
It is forming a Right angle triangle
.
In
,
and
.
Clearly see that we need to find measure of angle
.
Using Trigonometric ratio:

So, 
Then 
Therefore, Angle made by ramp with ground is ≈
Volume of prism= (Area of the trangle)*lenght
Area of the Triangle= (b*h)/2=7 ft *5 ft /2=35 ft /2=17.5 ft²
lenght is 8 ft
Volume= 17.5 ft² * 8 ft = 140 ft³
