Answer:
42 feet of string
Step-by-step explanation:
First, draw a diagram of the string, the height and the angle.
the length of the string is equal to the hypotenuse of the triangle
let length of the string=x
sin(θ)=opp/hyp
sin(72°)=40ft/x
x=40ft/sin(72°)
x=42.05848897ft≈42ft
Answer:-
1. False. A square is always a rhombus.
2. True. When all sides are equal in a rectangle then it is square.
3. False. In parallelogram opposite sides are equal .But kite is grouped into two pairs of congruent sides that are adjacent to each other. Thus A parallelogram can never be a kite.
4.True. A rhombus with interior angle 90° is square.
5.True. A trapezoid is a quadrilateral who has two opposite sides which are parallel to each other but kite is grouped into two pairs of congruent sides that are adjacent to each other.It may not have one pair of opposite parallel sides. Only rhombus is a kite which can be trapezoid.
You cant make a triangle with the combination 2,8 and 14, nor 2, 8 and 16 nor 2 , 14 and 16.
