The black triangle was transformed to make the gray triangle. Write an
sergeinik [125]

Answer:

m<4 = 117 degrees

Step-by-step explanation:

Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.

Angles on one side of a line add to 180 degrees.

180 - 63 = 117

Given △ABC≅△JKL, m∠B=55°, and m∠L=25°, what is the measure of ∠J?
8_murik_8 [283]
For the answer to the question above, 
<span><J = 100
</span><span>because they are similar they have the same angles
</span>The two triangles are similar, so they must have corresponding angles. Thats one way to define similarity, it can dilate (zoom in /zoom out) , but the angles are preserved. You can also define similarity in terms of the proportionality of the sides. 

"Given △ABC≅△JKL"

The order of the letters counts. 
<A = <J
<B = <K
<C = <L

<span>now you can draw two generic triangles, which have the same three angles, but label the angles accordingly, so they match up.
</span>
<span>then by correspondance we can fill in
</span>nightowlthe third angle can be found by the fact that 
the three angles must add up to 180.

Write an equation of the line that passes through (9, 2) and is parallel to the line below
Alex777 [14]

Answer:

y=5/3x-13

Step-by-step explanation:

We must use the point-slope form(parallel lines have the same slope, remember that!)

y-y1=m(x-x1)

y-2=5/3(x-9)

y-2=5/3x-15

y=5/3x-13
