I WILL TRY AND FIGURE IT OUT RQ
I think it’s the triangle
<span>If you have an equilateral triangle, the median is also the altitude so - That means that if you draw altitude, it will bisect the base of the triangle and meet at two right angles. That gives you two of the measurements for the right triangle - the side (6) hypotenuse, and the base (3). You can then figure out the height using the Pythagorean as you have the a and the c for the theorem. Then you can use 1/2 base times height to find the area.

Multiply the x by 4, then add 3. ( 4×

+3= 5 ). Keep doing that for the rest. Hope this helped a little. If you have any questions, you can message me if you would like.
