A trapezoid is a quadrilateral because it has 4 sides. A quadrilateral is not always a trapezoid because a quadrilateral can be any shape as long as it has four sides.
I may not make sense but I hoped this helped! :)
Answer:
A
Step-by-step explanation:
this is true due to the ratio of a 30-60-90 triangle, which is 1-2-sqrt(3). The 12 corresponds to the sqrt(3), which means that the 1 corresponds to 4sqrt3 and the 2 to 8sqrt3.

Answer:
B. Three bags
Step-by-step explanation:
For this problem you want to first find the area of the triangle so let's use the formula: 1/2*b*h. We can see in the picture that your base is 20m and your height is 6m so let's plug in your values to the equation and you'll get 1/2*6*20. Let's then multiply and we'll get 60.
The problem then states that one bag of topsoil is 20 square meters while our area of the triangle is 60sq. meters. Divide, 60/20=3 therefore you will need 3 bags of top soil for the entire triangular flower bed.
Answer:
x = 345/7
Step-by-step explanation:
7x/15 - 1 = 22
Add 1 to each side
7x/15 - 1 +1= 22+1
7x/15 = 23
Multiply each side by 15/7 to isolate x
15/7 * 7/15 x = 23 *15/7
x = 345/7
