HELP// On a piece of paper, use a protractor to construct a triangle with angle measures of 20° and 30°.

1 answer:

3 0

Add the two angles together then subtract 180 to find the third angle which equals 130 degrees so you have all your angles now you need the definitions for acute, obtuse, and right angle

right angle has a 90 degree angle so that cant be it

<span>an acute angle is less than 90 degrees so that is not it
</span>
obtuse angle is larger than 90 degrees so that must be the correct answer.. the correct answer is obtuse

The width of a rectangle is 15 ft. shorter than its length. Its perimeter is 262 ft. Let l equal the length of the rectangle.

masha68 [24]

Let the length be l.
For now, let's make the width be w.
Additionally, l = w + 15. Using this equation, width can also be written as l - 15.
The perimeter of a rectangle is length + length + width + width. This can also be written as l + l + (l-15) + (l-15) = l + l + l - 15 + l - 15 = 4l - 30.
Using this equation:
4l - 30 = 262
4l = 292
l = 73

4(w + 15) - 30 = 262
4w + 60 - 30 = 262
4w + 30 = 262
4w = 232
w = 58
