The perimeter of the triangle is 40 units
<h3>Perimeter of a triangle</h3>
From the question, we are to determine the perimeter of the given triangle
From the given diagram, we can observe that the triangle is a right triangle
The vertical length of the triangle is 15 units
and the horizontal length of the triangle is 8 units
Thus,
We can find the hypotenuse by using the<em> Pythagorean theorem </em>
Let the hypotenuse be h
Then,
h² = 15² + 8²
h² = 225 + 64
h² = 289
h = √289
h = 17 units
Now, for the perimeter of the triangle
The perimeter of a triangle is the sum of all its three sides
Thus,
The perimeter. P, of the triangle is
P = 15 + 8 + 17
P = 40 units
Hence, the perimeter of the triangle is 40 units

Answer:
N = 8/4
Step-by-step explanation:
Multiply all terms by n and cancel:
1/2+1/2+1/2=7N
8/7=7n (Simplify both sides of the equation)
7n=8/7/7
-
7
(Divide both sides by 7)
n=
8/49

Answer:
30/11
Step-by-step explanation:
Let's say x = 2.7272727272... If we multiply both sides by 100, we get:
100x = 272.7272727272...
We now have the equations:
100x = 272.7272727272...
x = 2.7272727272...
Let's subtract the second from the first. Doing so results in 99x on the left. On the right, the entire repeating part (72727272...) cancels out and we're just left with 272 - 2 = 270:
99x = 270
Divide by 99 on both sides:
x = 270 / 99
Simplify:
x = 30 / 11
The answer is 30/11.
