Answer:
The answer is B. 70
Step-by-step explanation:
First, since K is the midpoint of line segment JL, JK must equal KL.
So, set 9x-1 = 2x+27 and solve.
7x=28 so x=4
Then, since they are asking for JL, using x=4, add together JK and KL.
So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
Answer:
Correct choice is B
Step-by-step explanation:
Unknown leg x in right triangle is opposite to the angle of the measure of 50°. Use the definition of the sine of the angle:

Hence,

Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)
Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14
Therefore, there is no solution.
Answer: it must be 2
Step-by-step explanation: all the others have ‘red’ as an option, yet red isn’t mentioned anywhere in the problem.
