Answer:

199 in.

Step-by-step explanation:

We already now what the bottom two sides lengths are but we need to find the length of the top 2 sides.

To find the side lengths we can use the area of the right triangle on the top with the area of 15 in. to do that we need to find the lengths of the two dotted red lines making the right triangle using process of elimination the lengths of the left side is 3 the bottom length is 10. the we use the Pythagorean theorem to find the length of the perimeter. 10^2+3^2=109 109/2= 54.5. the length of the top two sides are 54.5. To now find the perimeter we add the length of one of the top 54.5 and one of the bottom 45 to get 99.5 then multiply it by 2 99.5*2= 199 the perimeter of the window is 199 in.

Step 1.

Use the compass. Place the point of the compass on Q

Draw an arc that intersects the lines of the angle. ( the arc should intersect lines PQ and RQ)

Step 2.

Locate the place where the arc intersects line PQ, put your point on the intersection, and draw another arc that is a little bit bigger than half of the angle. Do the same for line RQ. (the result should be that the two arcs you just drew form a curved x. The arc that you drew in step 1 also should be running through the middle of your x)

Step 3.

You now should have a total of three arcs. Find the point where all three arcs intersect, and draw a line from the point to point Q

Answer:

The y-intercept of m is less than the y-intercept of n.

Step-by-step explanation:

y-intercept of a function:

The y-intercept of a function is the value of y when $x = 0$

Function n represents a cubic function that passes through the points (-1,0) and (0,2).

When $x = 0, y = 2$ , and thus, the y-intercept is y = 2.

Function m:

When $x = 0, y = -6$ , and thus, the y-intercept is y = -6, which is a smaller number than 2, so the y-intercept of m is less than the y-intercept of n, and the correct answer is given by option A.
