The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse. 

If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.

Answer:

Step-by-step explanation:

All the interior angles are of measure 60 degrees.

We want to find the height of this triangle.  Call it h.  On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.

The ratio of height to base is the tangent of 60 degrees:

                                    h

tan 60 degrees = --------------

                                     5

                                                  h

and tan 60 degrees = 1.73  = ------

                                                   5

Multiplying both sides of this equation by 5 yields h = 8.66.  This is |BD|.  This is the same as Answer B.

Step-by-step explanation:

c+\frac{1}{4}c

Rewrite the expression

= 1c+\frac{1}{4} c

Add

= 1\frac{1}{4} c

Therefore, c+\frac{1}{4}c is equal to 1\frac{1}{4} c.

I hope this helps!
