It make it 121 instead of 118 because there is an extra number and median is the middle of a data set so the number of numbers is important.
Log 3 is the correct answer
Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
Answer:
<h2>x = 120°</h2>
( if given triangle is equilateral triangle)
Hope this will help you.
Answer:
14
Step-by-step explanation:
To find the perimeter, you need to add the lengths of each side.
In order to find the length of each side, imagine each side of the given triangle is the hypotenuse of an imaginary triage and use the Pythagorean Theorem (a² + b² = c²).
For the top side, I see an imaginary triangle with one side of 3 and the other side of 1. This means the length of the top of the given triange is √10:
3² + 1² = c²
9 + 1 = c²
10 = c²
√10 = c
For the left side, my imaginary triangle has one side of 5 and the other is 1. The length of this side is √26:
5² + 1² = c²
25 + 1 = c²
26 = c²
√26 = c
For the right side, I see a triange with two sides of 4 and the hypotenuse is √32.
This means the triangle in our question has side of √10, √26, and √32
If I add all of these up on a calculator, I get 13.918 which rounds up to 14 because the question wants the nearest whole unit.
