Step-by-step explanation:

Either one should work.

An isosceles triangle is a triangle where two angles are the same & the third angle is the supplement of their sum.

If you wanted the matching angles to be 70 & 70, your final angle would be 40 because:

70 + 70 = 140

180 - 140 = 40

If you wanted the supplement angle to be 70, your matching angles would be 55 & 55 because:

180 - 70 = 110

110 / 2 = 55

Hope this helped. :)

Write the equation of a line that is parallel to x

borishaifa [10]

Answer:

x=-3

Step-by-step explanation:

Hi there!

1) Determine the slope

Parallel lines always have the same slope. However, the given line x=8 is a vertical line organized in the form x=d, where d is the x-intercept. Therefore, the slope is undefined, and our line will also have an undefined slope.

Now, because this line will also be a vertical line, it will also be organized like:

x=d

2) Determine the x-intercept (d)

Note that all the points a vertical line passes through will have the same x-coordinate. We're given that this line passes through the point (-3,-2), so therefore, the x-intercept will be (-3,0).

Plug this into x=d:

x=-3

I hope this helps!

Answer:

(B) Negative

Step-by-step explanation:

You can try an example:

c = 1, d = -1

c/d = 1/-1 = -1 . . . . negative

Additional comment

The sign of the result of multiplication and/or division of any number of factors will be negative if there are an odd number of minus signs involved. It will be positive if there are an even number of minus signs involved.

The width of a rectangle is 5 more than twice the length. the perimeter of the rectangle is 28 in. what is the length and width

ycow [4]

Perimeter is P = 2l + 2w. From the question you know that w = 2l + 5 and that P = 28. To find l, plug the expression for w into the perimeter equation:

28 = 2l + 2(2l + 5)

28 = 2l + 4l + 10

28 = 6l + 10

18 = 6l

3 = l

Now find w by plugging 3 into its equation - w = 2(3) + 5. w = 11

Lastly, check your work by plugging everything back into the perimeter equation: 28 = 2(3) + 2(11), which is 28 = 6 + 22. Correct! So the length is 3 in and the width is 11 in.
