8 0

Answer:

9) QR = 4.0

10) AC = 4.1

Step-by-step explanation:

Tan = Opps. / Adj.

9)

Tan(60) = 7 / QR

QR = 7 / Tan(60)

QR = 7 / 1.732

QR = 4.0415

QR = 4.0

10)

Tan (27) = AC / 8

AC = Tan(27) * 8

AC = 0.5095 * 8

AC = 4.076

AC = 4.1

To make the second number in this ratio be 1, you need to multiply the whole ratio by 7/4:

  (7/4)(5/7) : (7/4)(4/7) = 5/4 : 1 = a : 1

  a = 5/4

Determine the slope of the lines parallel and perpendicular to -4x+3y=11
andreev551 [17]

Answer:

parallel = 4/3

perpendicular =-3/4

Step-by-step explanation:

Solve for y

-4x+3y=11

Add 4x to each side

3y = 4x+11

Divide by 3

y = 4/3 x +11/3

This is in the form y = mx+b where m is the slope

m =4/3

The parallel line has the same slope

parallel slope is 4/3

The perpendicular line has a negative reciprocal slope

m = -(1 /4/3) = - 3/4
