Answer:

Option (A)

Step-by-step explanation:

AE and RV are the two line segments intersecting at a point N.

Therefore, ∠ANR ≅ ∠ENV [Vertical angles are equal in measure]

(8x + 12)° = (5x + 57)°

8x - 5x = 57 - 12

3x = 45

x = 15

Since, m∠ENV = 5(15) + 57

= 75 + 57

= 132°

Therefore, Option (A) will be the answer.

The area of the following equilateral triangle is 62.4 square feet that is he height

Vikentia [17]

The height of this triangle would be 10.4

In order to find this, you first must find the length of the sides. Using a manipulated formula for area of an equilateral triangle, we can determine the lengths of the side. Below if the formula.

S = $\frac{2}{3}3^{\frac{3}{4}} \sqrt{A}$

In this, S is the length of the side and A is the area. So we plug in and get:

S = $\frac{2}{3}3^{\frac{3}{4}} \sqrt{62.4}$

S = $\frac{2}{3}3^{\frac{3}{4}} 7.89$

S = 12

Now that we have the side as 12, we can use the Pythagorean Theorem to find the height. If you split a equilateral triangle down the middle, you are left with two right triangles. Using this right triangle, the hypotenuse would be 12, the first leg would be 6 (half of the base) and the height would be the other leg. So we plug in and solve.

$a^{2} + b^{2} = c^{2}$
