Use the number line below, where RS=6y+4, ST=4y+7, and RT=61. a. What is the value of y? b. Find RS and ST.

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

step-by-step explanation:

96 39 cause 135 -96=39 im smart (i used a calculater)

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
