Given: △abc, m∠a=60°, m∠c=45°, ab=9 find: perimeter of △abc, area of △abc

The perimeter is 32.31

Step-by-step explanation:

1. You can use the Sines Law, as following:

2. The sum of the interior angles of a triangle is 180°, therefore, you can calculate the angle B:

°

3. Let's find BC:

4. Now, calculate AC:

5. Therefore, the perimeter is:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

two data sets with the same median will not have the same varaibility
