Answer:
a=14
Step-by-step explanation:
a= 32- (10) - (8)
a= 32-10-8
a=14
Answer:
cot θ = √15 / 7
Explanation:
csc θ = 1 / sin θ
In a right angled triangle, sin θ = opposite / hypotenuse
This means that:
csc θ = hypotenuse / opposite = 8 / 7
So, we have:
opposite = 7 units and hypotenuse = 8 units
We will use the Pythagorean theorem to get the adjacent side as follows:
(hypotenuse)^2 = (opposite)^2 + (adjacent)^2
(8)^2 = (7)^2 + (adjacent)^2
(adjacent)^2 = 15
adjacent = √15 units
Now, we want to get the value of cot θ.
We know that:
cot θ = 1 / tan θ
Since tan θ = opposite / adjacent
Therefore:
cot θ = adjacent / opposite = √15 / 7
Hope this helps :)
Answer:
Step-by-step explanation:
Let the sides of triangle be a, b and c
<u>Perimeter</u>
<u>New sides </u>
<u>New perimeter </u>
- Pn = 12a + 12b + 12c = 12(a+b+c) = 12*40 = 480 ft
Correct choice is D
Number 1
Because it varies how much time each student spends on the computer.
Y=0.5x-0.5
( u find the slope using rise/run then after finding the slope u use the equation and a point on the graph to find the y-intercept
