How to solve parallel lines with transversal?

The 128° angle and the top right exterior angle are corresponding angles, which means they have the same angle measurement. The top right exterior angle is also 128°.

The ? angle and the bottom right exterior angle are also corresponding angles, so they will have the same measurements.

To determine the ? angle, we know that a line is 180°. So if we add the 128° angle and the bottom right exterior angle, they will equal 180°.

When we determine the bottom right exterior angle, we know the ? angle will be identical because they are corresponding angles.

180° of a line - 128° angle= bottom right exterior angle
180-128= 52°

Bottom right exterior angle= 52°

Therefore the ? angle also equals 52°.

I wish the angles were labeled so it would be easier to explain. I hope this makes sense.

Hope this helps! :)

The angles have special names identifying their positions with respect to the parallel lines<span> and </span>transversal<span>. They are corresponding angles, alternate interior angles, or alternate exterior angles. An angles is congruent to its matched angle.

For the functions f(x)=−7x^2−x and g(x)=9x^2−4x, find (f−g)(x) and (f−g)(1)
musickatia [10]

Answer:

See below.

Step-by-step explanation:

f(x)=-7x^2-x\\g(x)=9x^2-4x\\(f-g)(x)=f(x)-g(x)\\(f-g)(x)=(-7x^2-x)-(9x^2-4x)\\(f-g)(x)=-7x^2-x-9x^2+4x\\(f-g)(x)=-16x^2+3x\\\\(f-g)(1)=-16(1)^2+3(1)\\(f-g)(1)=-16+3=-13

Please help me asap i will mark a branlist number 7
SVETLANKA909090 [29]

Answer:

When doing square roots the opposite is squaring so, to find one that is more than 12 and less that 13 would be finding one that is in between √144 and √169

That leaves your answer as √150, because it is more than √144 (which is 12) and less than √169 (which is 13)

B √150

Hope this helps ;)
