Length of longer leg = 9.4 tan 60 = 16.28 feet
Length of hypotenuse = 9.4 ÷ cos 60 = 18.8 feet
Perimeter of triangle = 9.4 + 16.28 + 18.8 = 44.48 feet

A kite string makes an angle of 41point3 degrees with the level ground when the kite is 114 ft high how long is the string?
In effect, you have a right-angled triangle with an adjacent angle of 41.3o and an opposite side of 114 feet. There are several ways to find the length of the string (which in effect is the hypotenuse of the triangle), but in this case, the quickest way is to use the sine ratio. For any right-angled triangle: sin angle = opposite/hypotenuse. Rearranging the equation: hypotenuse = opposite/sin angle hypotenuse = 114/sin 41.3o hypotenuse = 172.7268362 feet. Therefore, the string is 173 feet in length correct to the nearest foot.
How long must a ladder be if it is to be leaned against a house at a point 9 feet above the ground resting at least 3 feet from the bottom edge of the wall?
This describes a right triangle. This triangle has a base (X ) of 3 ft, a opposite side ( Y) of 9 ft. So, you are looking for the hypothenuse. Use the Pythagoreum theory. In this case. Your ladder length is called H. H^2 = X^2 + Y^2 H = sqrt X^2 + Y^2
A ladder rests against a wall the top of the ladder reaches 15 feet up the wall and makes an angle of 53 with the wall how long is the ladder?
If the wall is straight and the ground level then this is an outline of a right angle-triangle. If the top of the ladder makes an angle of 530 with the wall then the bottom of the ladder must make 370 to the ground. Use the sine ratio to find the length of the ladder (which will be the hypotenuse) sin = opp/hyp rearranged to hyp = opp/sin hyp = 15/sin370 = 24.92460212 feet So the length of the ladder is 25 feet correct to the nearest foot.
A tree 40 feet high casts a shadow 58 feet long find the measure of the angle of elevation of the sum?
Tangent (theta) is cosine / sine, or Y / X.Tangent (theta) is 40 / 58Theta = 34.6 degreesSince we are dividing cosine by sine, the hypotenuse does not matter as it cancels out.
What is the coversion of 3 feet into meters?
3 feet = 0.9144 meters. (multiply feet by 0.3048 to get meters).
What is the area of an equilateral triangle that has a perimeter of 71 feet?
Find the area of an equilateral triangle if its perimeter is 18 ft
The perimeter of a triangle is 32 feet and one side is 3 feet shorter what is the maximum length of each side of the triangular area?
12
The perimeter of an equilateral triangle is at most 57 feet. What could be the length of a sides?
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
How many square feet in a 84 feet perimeter?
Perimeter of which geometry (square, circle, rectangle, triangle, ...)
What is the length of an equilateral triangle if the perimeter is 12 feet?
4 feet
The hypotenuse of a triangle is 10 feet long The longer of the two legs is two feet longer than the other Find the length of the shorter leg?
The shorter leg is 6 feet long
The hypotenuse of a triangle is 15 feet long The longer of the two legs is three feet longer than the other Find the length of the shorter leg?
The shorter leg is 9 feet long
The perimeter of an equilateral triangle is 156 feet find the length of each side?
52+52+52 156
What is the perimeter to a triangle that has two sides that are 14ft and one side with 9ft?
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
What is the perimeter of an equilateral triangle that mesures 8ft on one side?
Perimeter = 3*8 = 24 feet
A triangle is 5ft by 5ft by 8ft perimeter of this triangle?
Just add together the length of the sides to get the perimeter. If the shape is 5 feet by 5 feet by 8 feet, just add together the sides: 5 + 5 + 8 = 18 feet.
