Question 5 of 10 Which system of equations is represented by the matrix below?
T0 712
514
O A. 7x = 12
y+ 5x = 14
O B. x+ 7y - 12
x+ 5y = 14
O c. 7y=12
x + 5y = 14

i dony know

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

77

step-by-step explanation:

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
