Find the length of AC Use that length to find the length of

Gekata [30.6K]

Answer:

1. AC = 5 cm

2. CD = 10.7 cm

Step-by-step explanation:

Looking at the left triangle, we see that AC is the side "opposite" of the angle given and AB is the "hypotenuse".

Which trigonometric ratio relates "opposite" to "hypotenuse"?

Yes, that's SINE.

So we can write:

$Sin(30)=\frac{AC}{10}\\AC=10*Sin(30)$

We know from 30-60-90 triangle, Sin(30) = 0.5, so we have:

$AC=10*Sin(30)\\AC=10*0.5\\AC=5$

Thus,

AC = 5 cm

Now, looking at right side triangle, we know AC, side "opposite" and we want to find CD, side "adjacent". Which trig ratio relates these 2 sides?

Yes, that's tan!

Thus we can write:

$Tan(25)=\frac{5}{CD}\\CD=\frac{5}{Tan(25)}$

Now using calculator, we get our answer to be:

CD = $\frac{5}{Tan(25)}=10.7$

CD = 10.7 cm

3. Classify the polygon below by its sides, convex/concave, and regular/irregular

wolverine [178]

Answer:

The polygon is a concave polygon

The polygon is irregular polygon

Step-by-step explanation:

Convex polygon is polygon that has all interior angles less than 180°

In a convex polygon, every diagonal of the figure passes only through interior points of the polygon

A line drawn through a convex polygon will intersect the polygon in exactly two points

Some of convex polygons can be regular polygons

Concave polygon is a polygon that has one or more interior angles greater than 180°

In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon

A line drawn through a concave polygon, can intersect the polygon in more than two points

Concave polygon never be a regular polygon

From the attached figure

∵ The polygon has one diagonal lies out the interior of the polygon

∴ The polygon is a concave polygon

∵ All the concave polygons are regular polygons

∴ The polygon is irregular polygon
