<span>Mica should have added 2 to 3 instead of 1 to 3.

She factored out a 2 on the righthand side, so adding 1 within the parentheses is equivalent to adding 2 outside the parentheses. Since this is an equation, what we do to one side, we must do to the other, so Mica should've added 2 to the lefthand side.</span>

What is the height of a right triangle with an angle that measures 60 degrees and a base of 14 adjacent to the 60 degree angle??
Arlecino [84]

Since this is a 30-60-90 right triangle, we know that the sides exist in the proportion 1:3‾√

:2. The shortest side, 1, is opposite the 30 degree angle. Since side X is opposite the 60 degree angle, we know that it is equal to 1∗3‾√

Or about 1.73. Finally, side Y is opposite the right angle, and it is twice the shortest side, or 2.

Silas is researching the cost of a specific souvenir he wants to buy on his international trip. Use the table to answer the ques
prisoha [69]

Answer:

Egypt.

Step-by-step explanation:

We need to set up our conversion factors for each currency.

British Pounds and Egyptian Pounds:

0.83 £ (Europe) = 1 U.S. Dollar

18 E£ (Egypt) = 1 U.S. Dollar

Cost of a Souvenir in Europe:

The cost of souvenir in Europe is 13£. Using our conversion rate, we get

13\pounds \cdot \frac{\$1}{0.83 \pounds}=\$15.66

Cost of a Souvenir in Egypt:

The cost of a souvenir in Egypt is 342 E£. So we have

342 \text{ E}\pounds\cdot \frac{\$1}{18 \text{ E}\pounds}=\$19

Based on our calculations, it is cheaper to buy a souvenir in Europe than in Egypt.
