<u>Answer:</u>
<em> 107</em>
<u>Step-by-step explanation:</u>
Sum of all angles is 180
12+BC+61 = 180
73+ BC = 180
73 - 73 + BC = 180 - 73
BC = 107
The centre of the circle is the middle of the two endpoints
so centre M is M(1,2) so the two last options aren't valid since those would be M(1,-2) and M(-1,2)
The radius would be half the distance of the two endpoints so
√(1+2)^2+(2-1)^2
√9+1
√10
so the answer is the second one
Answer:33
Step-by-step explanation:
x-y=4 or x=y+4
2x=3y+3 or x=1.5y+1.5
x=y+4 and x=1.5y+1.5 so
y+4=1.5y+1.5 or 2.5=0.5y or y=5
plug y=5 into x=y+4 and you get x=9
plug in y=5 and x=9 into 2x+3y and you get 2*9+3*5=18+15=33

Distance between points is given by the formula:
We will plug in the coordinates:
