What is the length of line segment SR?

Step-by-step explanation:

Using Pythagorean theorem.

16^2 + (RT)^2 = 20^2

256 + (RT)^2 = 400

(RT)^2 = 144

RT = 12

Using altitude theorem to find ST:

16/12= 12/ST

16ST = 144

ST = 9

Using Pythagorean theorem again:

12^2 + 9^2 = SR^2

144 + 81 = SR^2

225 = SR^2

SR= 15

Final SR= 15

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
