The figure below shows a triangular wooden frame ABC. The side AD of the frame has rotted and needs to be replaced:
What is the length of the wood that is needed to replace AD?

6.8 inches
6.2 inches
3.2 inches
2.8 inches

6.8 inches

Step-by-step explanation:

You can find the length of AD by finding the length of AB and DB, and then subtracting. Since 30+15=45, this is a 45-45-90 isosceles triangle, meaning that AB=16 units. DB can be found with a little trigonometry:

Subtracting this from the length of AB, you get about 6.76 inches, which rounds most closely to 6.8. Hope this helps!

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
