Find the value of X and Y

Svet_ta [14]

Answer:

All triangles' angles must add up to 180 degrees. An equilateral triangle has 3 equal sides and degrees. If it gives the angle of one all the other angles are the same. For x you see the parallel line below it with the line to the left going through with the same angle as the one below. The angles are the same and if it is labeled in one then it is the same in the other.

Principal Lopez asked her 500 students to vote on the school's annual gift. 300 students voted to donate a telescope for the sci

Maksim231197 [3]

Using the percentage concept, it is found that 60% of the students voted to donate a telescope.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem:

The total amount is the number of students, which is of b = 500.

300 voted to donate, hence a = 300.

The percentage is given by:

$P = \frac{300}{500} \times 100\% = 60\%$

60% of the students voted to donate a telescope.
