1. Given that JKLM is a parallelogram, what is the x-coordinate of L?
J(-2, 0)
K(b, 0)
I
M (0, -c)
L
Batc
C b-a
A a-b
D b + a
E b + c

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

parallelogram is the   answer

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
