Answer:
x = 7
Step-by-step explanation:
Using Cramer's rule, the value of x is ...

x = ((2)(-2) -(22)(3))/((-1)(-2) -(4)(3)) = (-4-66)/(2-12) = -70/-10
x = 7
Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!

∠K = 3(7)+3 = 24
∠L =10(7)-4=66
Answer:
B) -15
