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 answer: SR= 15

Hope this helps!

Which of the following equations uses the commutative property of addition to rewrite 1/3 + 2/5?

luda_lava [24]

The commutative property states that you can invert the order of the terms of a sum:

$a+b=b+a$

So, if you start with

$\dfrac{1}{3}+\dfrac{2}{5}$

Applying the commutative property you'll get

$\dfrac{2}{5}+\dfrac{1}{3}$

-7x-3x+2=-8x-2 can you please show your work how

iVinArrow [24]

Answer:

x = 2

Step-by-step explanation:

Given

- 7x - 3x + 2 = - 8x - 2 ← simplify left side

- 10x + 2 = - 8x - 2 ( add 8x to both sides )

- 2x + 2 = - 2 ( subtract 2 from both sides )

- 2x = - 4 ( divide both sides by - 2 )

x = 2
