Answer:

x=17

Step-by-step explanation:

ok so since lines PR and RQ are congruent (we know because of the lines on them), that means angles P and Q are also equal.

now we can set up the equation to find x like this:

29+29+(8x-14)=180 (180 because the three angles of a triangle always equal 180)

x=17

1<br> Determine the number of solutions for the equation.<br> - 3(42x +46) = -15(-22-9x)
kkurt [141]

Answer:

x=-52/29

Step-by-step explanation:

-3(42x+46)=-15(-22-9x)

-126x-138=330+135x

-126x-135x-138=330

-261x-138=330

-261x=330+138

-261x=468

x=468/-261

x=-52/29

Select all TRUE statements : A - Dilation always increase the length of shapes or line segments. B- Dilations of an angle are co
timurjin [86]

Hi!

A is <u>FALSE</u> - If you shrink a shape, it is not increased a shape, yet it is still dilating.

B is <u>TRUE</u> - When you dilate an angle, you're really just shortening or lengthening the sides, but the angle isn't changing.

C is <u>FALSE</u> - Explained above.

D is <u>FALSE</u> - Two triangles that are congruent are <em>exactly the same, </em>therefore if you dilate a triangle, you are changing the size so they are not the same.

E is <u>TRUE</u> - Similar shapes are always the same <em>except for their size. </em>When you dilate a shape, you only change the size, therefore they are equal in every other way and they are similar.
