Answer:
You know that XZ is 15 and the whole perimeter of the triangle is 50. WZ is going to be the same length as WX due to the lines saying that they are equal.
Your first step is to take 50-15=35, we did this because we already know the length of one side and can take that off from the whole.
The next step is to divide 35 by 2, because both sides are going to be the same length.
35/2=17.5
You final answer would be 17.5
Hope this helps ;)
You are the correct one. If the person is not able to proof, and if you are rather sure about your answer, it is better to take your own answer instead :)
-9d = 63
<Multiply both sides by (-1)>
=> (-1) × (-9d) = (-1) × 63
=> 9d = -63
=> d = -7
The answer is C. 14
35/5=7
7•2=14
I think a straight edge will be best for you to use
