How to find missing angles

Since we know that a triangle equals to 180 degrees, we should start by adding together the two known angles inside the triangle. To determine to measure of the unknown angle, be sure to use the total sum of 180 degrees. If two angles are given, add them together and then subtract from 180 degrees. If two angles are the same and unknown, subtract the known angle from 180 degrees and then divide by 2.

On a recent day, one U.S dollar was worth 0.64 euros. If you were to exchange 126 euros on that day, how many U.S. dollars would

Dimas [21]

Answer: $196.88

Step-by-step explanation:

It is given that the rate of 1 US dollar = 0.64 euros.

Then, 1 euro = $\frac{1}{0.64}\text{ dollars}$

⇒ 1 euro =1.5625 dollars

Now, 126 euros = $126\times1.5625$

$\Rightarrow126\text{euros} =196.875\approx196.88\text{ dollars}$

Hence, If we exchange 126 euros on that day, then we would receive 196.88 dollars.
