Answer:

The only correct choice is ' E ' .

Step-by-step explanation:

A. Trapezoid . . . no; a trapezoid has one pair of parallel sides.

B. Parallelogram . . . no; a parallelogram has two pairs of parallel sides.

C. Rhombus . . . no; a rhombus is a parallelogram AND all four of its sides have the same length.

D. Square . . . no; a square is a parallelogram AND it's a rhombus AND its angles are all 90 degrees.

F. Rectangle . . . no; a rectangle is a parallelogram AND its angles are all 90 degrees.

The shape in the picture doesn't have ANY of these characteristics or features. All it has going for it is four sides. That's a 'quadrilateral'.

What’s the answer to this?

inna [77]

Since the triangle is equilateral, all its angles are equal to 60°

AO is the bisector⇒∠OAD = 30°

AO is the hypotenuse, ∠OAD = 30°⇒

OD=5*2=10m

By the Pythagorean theorem

$10^2=AD^2+5^2\\AD=\sqrt{100-25} \\AD=\sqrt{75}$

$AC=AD+DC=2\sqrt{75}=10\sqrt{3}$

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

$S=\frac{(10\sqrt{3})^2\sqrt{3} }{4} =\frac{300\sqrt{3} }{4} =75\sqrt{3} m^2$

Answer: A) $S=75\sqrt{3}$ m²
