Your answer is A.) for ur problem
If you decrease number by 50% of that number you are basically dividing with 2 hence the answer is 15.
Angle 56 is vertical to the blank angle so that means they are equal.
So now 56, 41 and x create a straight line, so they are equal to 180.
180 = 56 + 41 + x
180 = 97 + x
83 = x
Hope this helps :)
Answer:
<em>The length of the side BC is 6 units</em>
Step-by-step explanation:
<u>Distance Between two Points in the Plane</u>
Given two points A(x1,y1) and B(x2,y2), the distance between them is:

We need to calculate the distance between B(7,5) and C(7,-1):


d=6
The length of the side BC is 6 units
