Answer:

<u>C</u>:  <em>3x + 80 + 2x = 180</em>

Step-by-step explanation:

A straight line is equal to 180 degrees total the find x, you would add the number within the line and make it equal to 180.

3x + 80 + 2x = 180

add like terms

5x + 80 = 180

subtract 80 from each side

5x = 100

divide each side by 5

x = 20

A ray and a line intersect to form ∠1 and ∠2 as shown below.
Oksi-84 [34.3K]

Answer:

STEP 3

Step-by-step explanation:

Francesca drew point (–2, –10) on the terminal ray of angle , which is in standard position. She found values for the six trigonometric functions using the steps below.

A unit circle is shown. A ray intersects point (negative 2, negative 10) in quadrant 3. Theta is the angle formed by the ray and the x-axis in quadrant 1.

Francesca made her first error in step 3 because the sine, cosine, and tangent ratios are incorrect, which also resulted in incorrect cosecant, secant, and tangent functions.

(1 point) let a=⟨−4,−3,2⟩a=⟨−4,−3,2⟩. find a unit vector in the same direction as aa.
sergij07 [2.7K]
A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2)   [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).

So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).
