Answer:

Step-by-step explanation:

The sum of the angles of a triangle should always add up to 180 degrees.

In this problem, they have given us 2 angle measures of the triangle - 53 degrees and 45 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.

I'm just going to do some simple math:

53 + 45 = 98 (sum of the 2 angles)

180 - 98 = 82 (subtracting 180 by the sum of the 2 angles)

However, we have only found the third angle in the triangle. The variable x is for the angle <em>supplementary </em>to the one we just found. Therefore, we must solve the angle measure of the supplementary angle x by doing 180 - 82 which equals 98.

Find the solution for y=2x-1 y=3x+2

ziro4ka [17]

ANSWER: (-3,-7)
Set them equal to each other so, 2x-1=3x+2 to find x. You should get x= -3

Then you plug in -3 for x to find Y for either y=2x-1 or y=3x+2. I’m picking y=3x+2 so when you plug in -3 to x it will be y=3(-3)+2 = -7 . So therefore y=-7

A broken rectangular shaped window is being replaced. It measures 24 inches by 18 inches. How many square inches of glass are ne

olya-2409 [2.1K]

Sorry, I can't draw a picture, but I can help answer the question...

The way to determine the area of a square or rectangle is to multiply the base and the height, which in this case, is 24 and 18. So 24 times 18 is 432. Therefore, the amount of glass needed to repair the window is 432 inches squared.

Hope that helps!
