<h2>75</h2>

- - - - - - - - - - - - - - - - - - - - - - - -

Beginning with an "If-then" statement ⇣

<em>If </em><em>2/5 = 30 </em><em>then</em><em> 1/5 = 15</em>

Now we have 1/5, let's make it 1 by multiplying x5.

<em>15 x 5 = </em><em>75</em>

- - - - - - - - - - - - - - - - - - - - - - - -

Good luck! :)

A certain triangle has a 30° angle in a 60° angle. Which must be a true statement about the triangle
Lady bird [3.3K]

Answer:

It is a right triangle.

Step-by-step explanation:

A right triangle is a triangle with at least one angle with 90 degrees.

We know that every triangle has 180 degrees. The other unknown angle is 180 - (30+60) = 180 - 90 = 90. That means that the other angle is 90 degrees. Therefore, it is a right triangle

We also know that in this triangle, that the square of one side plus the square of another is side is equal to the square of the hypotenuse of the triangle. (According to Pythagorean theorem)
