Answer:

B.

Step-by-step explanation:

sin∅ = opposite side over hypotenuse

cos∅ = adjacent side over hypotenuse

To find <em>x</em>, there are multiple ways:

tan72° = 6/x

x = 6/tan72°

cos72° = x/15

What is the slope of the line?<br> 3x-4y=7
Vinvika [58]

Answer:

3/4

Step-by-step explanation:

3x - 4y = 7.....subtract 3x from both sides

-4y = -3x + 7 ...now we divide both sides by -4

(-4/-4)y = (-3/-4)x + (-7/4)...simplify

y = 3/4x - 7/4

y = mx + b

y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
