A carpenter is making a backyard deck in the measurements, he has determined that he needs to make a support triangle with an area 40m ^ 2 He knows that the base must be 3 less than 2 times the height the base is represented by 2x - 3 and height equals . Find the equation that correctly shows the area of the triangle.

the answer is c

step-by-step explanation: i took a test with this question on it

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
