Answer:

A. 3.5

Step-by-step explanation:

The perimeter is just the sum of all of the side lengths. The sides of this triangle are n inches, (n + 5.2) inches, and (2n + 3.4) inches.

So, your equation is n + n + 5.2 + 2n + 3.4 = 22.6 inches.

You can combine like terms (adding together all of the n's and all of the numbers) to simplify your equation to 4n + 8.6 = 22.6 inches.

Subtract 8.6 from both sides of the equation to get 4n = 14, and divide both sides by 4 to get n = 3.5.

Hope this helps! :)

what dose a point represents: a) line segment b) a location c) intersection of a plane d) none of the above

meriva

Answer:

(B) A location

Step-by-step explanation:

If you have a point on a graph or number line, it always represents a certain location on the graph.

For instance, if we have a point on the x=3 line and the y=4 line, the point would represent the location (3,4).

Hope this helped!

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)

Eduardwww [97]

Given:

The figure of a right triangle. $PO=12,m\angle O=y^\circ$ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

$\sin\theta=\dfrac{Perpendicular}{Hypotenuse}$

In the given right angle triangle,

$\sin y^\circ=\dfrac{7}{12}$

$y^\circ=\sin ^{-1}\dfrac{7}{12}$

$y^\circ=35.685335^\circ$

$y^\circ\approx 35.69^\circ$

Therefore, the measure of angle y is $y^\circ =35.69^\circ$ .
