Answer:
a. x = 8
b. m<B = 140
Step-by-step explanation:
a.
m<A = m<B
40 = 5x
x = 8
b.
m<A + m<B = 180
m<B = 180 - m<A
m<B = 180 - 40
m<B = 140
12,089 is less than 12,098
The first choice is the correct one.
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)
Multiply both by -1: 113.75-112=1.75
multiply answer by -1: -1.75
