Answer:

D

Step-by-step explanation:

Because the shape JKL was rotated about the origin....where if you draw a line from point K(3,4) to the origin and another line from the origin to the image point of K...which is (-4,3)....;and the angle between the two lines is 90 degrees

And if you try it with any point...J and L...to their images...(-8,3) and (-4,7) respectively...it should still produce a 90 degree angle at the point O

Those 2 questions I need help with . find sec θ and tanθ
Zielflug [23.3K]

STEP - BY - STEP EXPLANATION

What to find?

The the value of secθ.

Given:

(4, 3)

⇒(x, y) = (4, 3)

Step 1

Draw a sketch.

Step 2

Substitute the values into the trig. ratio formula below.

tan\theta=\frac{opposite}{adjacent}

From the sketch above, opposite = 3 and adjacent = 4

tan\theta=\frac{3}{4}

Step 3

Find the value of the hypotenuse side using Pythagoras theorem.

let h be the hypotenuse side.

\begin{gathered} h^2=4^2+3^2 \\  \\ =16+9 \\  \\ =25 \\  \\ h=5 \end{gathered}

Hence, hypotenuse = 5

Step 4

Substitute the values into the formula below:

\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\  \\ =\frac{4}{5} \end{gathered}

But,

sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{4}{5}}=\frac{5}{4}

ANSWER

secθ= 5/4

tanθ=3/4
