One of the angles in an intersecting line mesures 30

1 answer:

7 0

Think of the point, P, where the lines intersect as the center of a circle. The four angles with vertex P add up to 360 degrees. The given angle and its paired vertical angle are both 30 degrees. So, the other two angles are also vertical angles with sum 300 degrees (so each of them is a 150 degree angle).

Find the midpoint of each line segment

devlian [24]

Answer:

( $\frac{7}{2}$ , $\frac{1}{2}$ )

Step-by-step explanation:

For this you use the midpoint formula

$(\frac{x_{2} +x_{1} }{2} ,\frac{y_{2} +y_{1} }{2} )$

the points would be (2,1) and (5,2)

The midpoint would be ( $\frac{7}{2}$ , $\frac{1}{2}$ )

Absolute value is simply the non-negative version of the number regardless of its symbol

So for the absolute value of 20? the answer is just 20.

For reference, the absolute value of -20 is also just 20.

Kyle walks 3 blocks south from his home to school, and jana walks 2 blocks north from her home to kyle's home. how far and in wh

Nostrana [21]

If Jana has to walk 2 blocks north to get to Kyle's home, then 3 blocks south to get to school, this means that she has just retraced the 2 blocks she walked to get to Kyle's home.

So the school is just 1 block south of Jana's home.

Would it make sense to state "a dilation has a scale factor of 1" explain your reasoning

adelina 88 [10]

It wouldnt be reasonable bc a scale factor of 1 would make no difference therefore meaning there is no dilation.
