Which figure is a trapezoid?

The answer would be a four sided shape with one set of parallel sides. Parallel sides are two sides that will never touch or intersect. To further explain, if we take the left and right sides of the trapezoids and extend them, they will eventually intersect meaning that they aren’t parallel. This will go for and trapezoid, no matter the side lengths. However, if we take the top and bottom sides of a trapezoid and extend them left and right, we will find that they will never intersect which is how we know that a trapezoid only has one pair of parallel sides.

Show algebriacally that the sum of two consecutive numbers is always odd

egoroff_w [7]

X + (x+1) = 2x+1
Here, 2x+1 is always odd
For example the value of x is 2 then we can say that,
x=2; x+1=3; 2x+1 = 5 [odd number(5)]
= 2 + 3 = 5

Two people are 100 feet apart on opposite sides of a tree. The angles of elevation from the people to the top of the tree are 30

We need to solve for the height of the tree given two angles and distance between the two observers. See attached drawing for a better understanding of the problem.
We derive to equations using SOH CAH TOA such as below:
sin30 = h / x
sin 45 = h / (100-x)

sin 45 (100-x) = xsin30
70.71 - 0.71x = 0.5x
70.71 = 1.21 x
x = 58.44

Solving for h, we have:
h = xsin30
h = 58.44 sin30
h = 29.22

The height of the tree is 29.22 feet.
