Answer:
±√6
Step-by-step explanation:
is your expression first muiltiply out the 10 to get 15n= 10n+10 3/n next subtract 10 n from both sides to get 5n=10+3/n multiply both sides by n to get 5n^2=13 combine both sides and use the quadratic equation to solve to get your solution of ±√6
Answer:
The answere is B - 28.7ft
Step-by-step explanation:
Sin(55) = y/35
y = 35 * Sin(55)
y = 28.7 ft
Answer:
B. 45 degrees
Step-by-step explanation:
We know that the square at the bottom corner means it's 90 degrees. Since there are 180 degrees in a triangle, we could do 180 - 90. Assuming it's perfectly symmetrical, we would divide 90 ÷ 2. This means that the angle measures 45 degrees.
Answer:
<h2>2</h2>
Step-by-step explanation:
Answer:
Step-by-step explanation:
Triangle MRN is created by folding an equilateral triangle by half. Since triangle MRN is right triangle, the equilateral triangle must be folded along the height drawn to one side.
In equilateral triangle with side length of a units, the height is and the height is greater than half the side because
The leg with length x units has the smaller projection (2 units long) than the leg with length y units has (6 units long).
This means the leg with length y units is the height of the equilateral triangle. If the leg with length y units is the height of the equilateral triangle, then the hypotenuse MN = 8 units is the side of the equilateral triangle and lex with length x units is half the side, so x = 4 units.
By the Pythagorean theorem,
