Find the area , you usually solve it by using the special right triangle , but its not 30,60, or 90 . so i don’t know how to solve it using it with 36 degrees

step-by-step explanation:

in which figure is point g a centroid

yes.. it's proven to be 36.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
