Answer:

Cosθ = 0.5145

Sinθ = 0.8575

Secθ = 1.9436

tanθ = 1.667

Step-by-step explanation:

From the figure attached,

Point P(-3, 5) is on the terminal side and AB is the initial side of the angle PAB.

If m∠PAB = θ

AB = \sqrt{(3)^{2}+(5)^{2}}

     = \sqrt{34}

     = 5.831

Then Cosθ = \frac{AB}{AP} = \frac{3}{5.831}

Cosθ = 0.5145

Sinθ = \frac{PB}{AP}

Sinθ = \frac{5}{5.831}

Sinθ = 0.8575

Secθ = \frac{1}{\text{Cos}\theta}

Secθ = \frac{1}{0.5145}

Secθ = 1.944

tanθ = \frac{PB}{AB}

tanθ = \frac{5}{3}

tanθ = 1.667

Solve equation<br><br> -2 • 4/5 = -3 1/2 • n
kogti [31]
16/155 = n


explanation

A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:

Maintain balance of the equation by applying the same operations to both sides of an equation

Isolate for the variable by collecting like terms

Use inverse operations to rearrange an equation


to show your work

-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
