What is the measure of X
Musya8 [376]

Answer:

<h2><em><u>X = 67</u></em></h2>

Step-by-step explanation:

The triangles' angles are congruent.

So,

J = H

67 = 67

I = K

X = X

Make the angles add

So,

46 + 67 = 113

Subtract from total

180 - 113 = 67

<h2><em><u>The angle is 67.</u></em></h2>

<em><u></u></em>

Hope this helped,

Help urgently please❤️ I’ll mark u brainlyest thank u
ELEN [110]

Answer:

-1/2 and 2

Step-by-step explanation:

Since you need y=mx+b you have to convert your equation to match this

So, 3x+6y=12

Subtract 3x from both sides to get the y term on the left side alone.

This leaves 6y=-3x+12

From there divide 6 from both sides to give you your y term alone on the left side completely.

That leaves you with y=-1/2x+2

Meaning your M=-1/2 and your B=2

Your graph then should have the start point be at y=2 from there move -1 spaces down the y axis, and go to spaces to the right. Making your line move between r and n
