Answer: 93,\ 34^{\circ}

Step-by-step explanation:

Given

For figure (i) both triangles are congruent

\therefore 8x-27=4x+33\\\Rightarrow 8x-4x=33+27\\\Rightarrow 4x=60\\\Rightarrow x=15

\Rightarrow PQ=8x-27\\\Rightarrow PQ=93

For figure (ii)

Two triangles WXZ and WZY are congruent

\therefore 9x-28=5x-8\\\Rightarrow 4x=20\\\Rightarrow x=5^{\circ}\\\Rightarrow \angle YWX=2(9x-28)\\\Rightarrow \angle YWX=2(17)\\\Rightarrow \angle YWX=34^{\circ}

Answer:

#1: -1.5, -0.5, 1/2, 1.5

#2:  -3, -1, 1.2, 2.3

Step-by-step explanation:

#1

First we have to figure out the correct order before we plot.

Find the biggest number:

looking at the number the biggest would be 1.5

Find the smallest number:

Looking at the number the smallest would be -1.5

Now that we have that we can easily figure out the rest...

(Going from least to greatest; like on a number line)

-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)

#2

(Use the steps from above to find the answer)

Biggest: 2.3

Smallest: -3

Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)

Hope this helps :)
