Question

triangle RST is an equilateral triangle; . line TX is perpendicular of line RS.

If RX = 3, then

RT = ?

Answer 1

Since TX is perpendicular to RS and the triangle is equilateral, then RX is just half the length of RS. since we know RX = 3

2RX = RS

2(3) = RS

RS = 6

And again it is an equilateral, so all the sides are the same, meaning RT = RS

RT = RS

RT = 6

Answer 2

thanx so much
