If two angles are known to be the same, the triangles are similar! If this is true, then by default the third angle will be the same. So, triangles that have two of the same angles MUST be similar!

If two of the interior angles are the same, the triangle is similar. If it is similar, the third angle will automatically also be congruent.

tester [92]

Answer:

<h2>The measure of angle B is 46.4°, approximately.</h2>

Step-by-step explanation:

We need to find the measure of angle B. Notice that it's a right triangle, where we already know the hypothenuse and the adjacent leg to the angle, that means we need to use the cosine trigonometric reason

cosB=\frac{adjacent}{hypothenuse}=\frac{20}{29}\\  B=cos^{-1}(\frac{20}{29}) \\B \approx 46.4 \°

Therefore, the measure of angle B is 46.4°, approximately.

Anita purchased a couch that was priced at $700. She will also have to pay 6% sales tax. How much will she pay in total for the
Zolol [24]

Answer:

$742

Step-by-step explanation:

To solve this, you need to figure out what 6% of 700 dollars is and then add that to 700. The easiest way to find the percentage of a number is to set it up in the equation:

6/100 = x/700  where 6 is the percentage of 700 (out of 100 because you can only get up to 100 percent in this case) and x is 6 percent of 700. when you cross multiply, you get 100x = 4200. Then you divide both sides by 100 to get x by itself. This will give you x = 42 Add this to 700 for 742 as the total amount that will be paid. Sorry if this first half was a little confusing

In the number 35.3816, the underlined three is __________ the other three.
Fantom [35]
Answer:
100 times bigger 

Explanation:
The given number is:
35.3186

Let's take a look at the first 3 on the left (the one in bold).
We will find that this 3 is in the tens position (10)

Now, let's take a look at the other 3 (the one directly after the point).
We will find that this 3 is in the tenth position (0.1)

Now, when multiplying the digit in the tenth position by 100, this digit would be in the tens position.
This means that the difference between the two positions is 100

Based on this:
The 3 in the tens position is 100 times greater than the 3 in the tenth position.

Hope this helps :)
