Solve for x.<br> 6x<br> (2x + 12)
Furkat [3]
It’s a straight line, and a straight line equals 180° so it would be:
180=6x+2x+12
180=8x+12
subtract 12 from both sides
168=8x
divide both sides by 8
21=x
the answer is 21 which is the second choice

Can someone please help me with the questions in the images. if they are correct i will mark as brainliest
valentina_108 [34]

Answer:

6) x=9.75

10) Triangle OMN ~ Triangle ODK; SSS ~

11) SSS ~ theorem

12) SSS ~ theorem

Step-by-step explanation:

For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice

For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.

For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.

For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
