Answer:
...
Step-by-step explanation:
can you show us the options of the drop-down menus?
The triangle that the height makes would be a 45-45-90 special right triangle. So the height is 3√2, and to find the area, it would be the average of the bases, 7, multiplied by 3√2. So the area of the trapezoid is 21√2.

G(x) x^2-11 is a translation of f(x) x^2 shifted 11 units down
<span>Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse. </span>
<span>The triangles are similar (right triangles which share an angle (A), so... </span>
<span>AD/AC = AC/AB </span>
<span>5/6 = 6/AB </span>
<span>AB = 6*6/5 = 36/5 = 7.2 </span>
<span>The answer to the first question is "C" </span>
<span>CD can be found using the Pythagorean theorem... </span>
<span>AD^2 + CD^2 = AC^2 </span>
<span>25 + CD^2 = 36 </span>
<span>CD^2 = 11 </span>
<span>CD = sqrt(11) = 3.3 </span>
