For the first part remember that an equilateral triangle is a triangle in which all three sides are equal & all three internal angles are each 60°. <span>So x-coordinate of R is in the middle of ST = (1/2)(2h-0) = h
And for the second </span><span> since this is an equilateral triangle the x coordinate of point R is equal to the coordinate of the midpoint of ST, which you figured out in the previous answer. Hope this works for you</span>
Answer
23.70
Proof
3Q+5+2-8-5=65 ~ Simplify
3Q-6=65 ~Cancel out the six
+6 +6 ~Add 6 to both sides since it is a 3Q=71 negative.
/3 /3 ~Cancel out the three.
Answer ~Divide both sides by 3
Q=23.66
Rounded Up
Q=23.70
Answer:
This is the farthest I could go in solving the equation. Is there anymore information about the problem? Unless you are looking for n which it would seem n would equal 10.
