Answer:

Supplementary

x=34

Step-by-step explanation:

The 2 angles are on a straight line. Therefore, they are supplementary. This means, that if the angles are added together, they must equal 180 degrees.

Therefore,

x+4x+10=180

Now, we have an equation, and can solve for x. To solve for x, we have to get x by itself.

First, combine like terms. Add the terms with a variable together.

(x+4x)+10=180

5x+10=180

Next, subtract 10 from both sides, because 10 is being added onto 5x.

5x+10=180-10

5x=180-10

5x=170

Now, divide both sides by 5, since 5 and x are being multiplied.

5x/5=170/5

x=170/5

x=34

So, the angles are supplementary and x=34

Answer: <span>A square inscribed in a circle.
</span>

Justification:

Note that by making two perpendicular lines that intersect each other in the center of the circle, he obtains 4 equidistant points on the circumference.

So, joining each pair of neighbouring points, the image will reveal 4 congruent sides joining at right angles (90°). This is the image of a square with the four vertices on the circumference.

RSB [31]

Answer:

$\begin{array}{cccc}&\text{Prefer Pizza}&\text{Do not Prefer Pizza}&\text{Total}\\\text{Prefer Punch}&23&29&52\\\text{Do not Prefer Punch}&66&7&73\\\text{Total}&89&36&125\end{array}$

Step-by-step explanation:

There are 125 members.

89 of them preferred pizza and 23 of 89 preferred punch, so 89-23=66 preferred only pizza.

52 members preferred punch, 23 of them preferred both pizza and punch, so 52-23=29 preferred only punch.

Now,

66 members preferred only pizza,

23 members preferred both,

29 members preferred only punch,

125-66-23-29=7 members did not prefer both

The two-way table is

$\begin{array}{cccc}&\text{Prefer Pizza}&\text{Do not Prefer Pizza}&\text{Total}\\\text{Prefer Punch}&23&29&52\\\text{Do not Prefer Punch}&66&7&73\\\text{Total}&89&36&125\end{array}$
