The hypotenuse of two triangles combined is 20.8 and ras has a leg of 6.37 that tes has a corresponding leg to which is 8.19. both triangles are similar. they are connected together to where s is a vertical angle. find the length of st

the correct answer is 5 6 and 7

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

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.
