We can use trigonometry to solve this problem. Sin=opposite/hypotenuse. So, sin(65)=22/x. ( 22 is opposite because it’s the opposite to the labeled angle (65 degree angle). X is the hypotenuse ( we can find the hypotenuse by finding the right angle, hypotenuse is always located opposite to the right angle, or it can be found just by looking at the picture, hypotenuse will be the longest side.). Next, cross multiplication can be used. It’ll look like this: Sin65/1=22/x Sin(65)x=22. X=22/sin(65). X=24.27.

Answer:

Rational

Step-by-step explanation:

$2^{-3}$ simplifies to $\frac{1}{8}$ .

Therefore, it is rational.

$2^{-3}\\\\\text {Apply negative exponent rule: } a^{-n} = \frac{1}{a^n} \\2^{-3}= \frac{1}{2^3}\\ \rightarrow 2^3 = 2*2*2=8\\\boxed{2^{-3}=\frac{1}{8}}$

1. Write a two-column proof.

Alexandra [31]

Answer:

Check it below, please

Step-by-step explanation:

Hi there!

Let's prove segment AB is perpendicular to CD. Attention to the fact that a two column proof has to be concise. So all the comments can't be exhaustive, but as short as possible.

Let's recap: An isosceles triangle is one triangle with at least 2 congruent angles.

Statement Reason

$\overline{AB} \cong \overline{AC}\\$ Given

$\widehat{ACB} \:bisects\: \overline{AB}$ Isosceles Triangle the altitude, the bisector coincide.

$\overline{AD} \cong \overline{DB}$ Bisector equally divide a line segment into two congruent

$m\angle CDA =m \angle CBD=90^{\circ}$ Right angles, perpendicular lines.

$\overline{CD}\perp \overline{AB}$ Perpendicular Line segment
