Given \qquad m \angle QPSm∠QPSm, angle, Q, P, S is a straight angle. \qquad m \angle QPR = 7x - 4^\circm∠QPR=7x−4 ∘ m, angle, Q, P, R, equals, 7, x, minus, 4, degrees \qquad m \angle RPS = 9x - 40^\circm∠RPS=9x−40 ∘ m, angle, R, P, S, equals, 9, x, minus, 40, degrees Find m\angle QPRm∠QPRm, angle, Q, P, R:

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

add the table and i will answer correctly

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
