Answer: a 68 c57 b55 I think
Step-by-step explanation:
A triangles angles add up too 180 so just subtract the sum and the two angles and you are done.
Yes, they will equal each other because the question says that the line is the perpendicular bisector of JK.
So,
25x-18=13x+90
12x=108
x=9
Now to find the length of JK, do 25(9)-18+13(9)+90
The answer is 414.
X+y=10 in y-intercept is y=-x+10. 10 is the y intercept. The ordered pair is (0, 10)
