Answer:

First answer.

Step-by-step explanation:

We know that a complete rotation would be 360°. If the figure is being rotated 90°, this is a quarter of a complete rotation.

When looking at the given answers, only the first answer seems logical.

Evaluate the six trigonometric functions of the angle 0

Alla [95]

# Sin θ = 9/15.

# Cos θ = 12/15.

# Cosec θ = 15/9.

# Sec θ = 5/4

Step-by-step explanation:

$by \: using \: pythagorian \: triplets$

${a}^{2} + {b}^{2} = {c}^{2}$

${9}^{2} + {12}^{2} = {c}^{2}$

$81 + 144 = {c}^{2}$

$225 = {c}^{2}$

$c = 15.$

$\sin θ = \frac{9}{15}$

$\cos θ = \frac{12}{15} = \frac{4}{5}$

$\csc θ = \frac{15}{9}$

$\secθ = \frac{5}{4}$

What is the equation of the line that is horizontal and goes through the y-axis<br> at -4?

Ivan

Y = mx + b, m = 0. The equation becomes y = b, where b is the y-coordinate of the y-intercept.

What is an angle between a side of a polygon and the extension of its adjacent side

jek_recluse [69]

I would say that the angle would be an exterior angle because it's usually between the side of the polygon connected by a line as an extension of the adjacent side.

here's an example. hope it helps!

Can someone help me with this math homework please!

Answer:

1st, 2nd and 6th options

Step-by-step explanation:

Given

$\frac{2}{3}$ - x + $\frac{1}{6}$ = 6x ( multiply through by 6 to clear the fractions )

4 - 6x + 1 = 36x ← option 1 will have the same solution set

----------------------------------------------------------------------

Adding the 2 fractions on the left side gives

$\frac{4}{6}$ + $\frac{1}{6}$ - x = 6x , that is

$\frac{5}{6}$ - x = 6x ← option 2 will have the same solution set

------------------------------------------------------------------------

From

4 - 6x + 1 = 36x ( add 6x to both sides )

5 = 42x ← option 6 will have the same solution set
