<span>Its given that the sum of the values of total angles of a triangle is 180. It is also given that angles a and b are equal and that value of c is 72. Thus we get the following equation:
a + b + c = 180
a + a + 72 = 180 since a = b
2a = 108
a = b = 54 and c = 72</span>
Answer:
S(0, 2)
Step-by-step explanation:
Midpoint Formula: 
Step 1: Plug in known variables
5 = (10 + x)/2
-8 = (18 + y)/2
Step 2: Solve
10 = 10 + x
x = 0
-16 = 18 + y
y = 2
Step 3: Write coordinates
(0, 2)
sub B = (x,y)
midpoint= ( (x-2)/2, (y+2)/2 )
(x-2)/2=1 and (y+2)/2=0
x-2=2 and y+2=0
x=4 and y= -2
B= (4,-2)
Unless refuted later in the equation, this statement would be True because they are normally giving you the data to work with to save you the time of finding it yourself.
