Answer:

x = 8 in

y = 8sqrt(2) in

Step-by-step explanation:

x = 8

AC = BC

Because opposite angles are equal.

8² + 8² = hyp²

hyp² = 64 + 64 = 128

hyp = sqrt(128)

hyp = 8sqrt(2)

Where sqrt is the square root

Find (r-s) (t-s) + (s-r) (s-t) for all numbers r, s, and t. (a) 0 (b) 2 (c) 2rt (d) 2(s-r) (t-s) (e) 2(r-s) (t-s)

lyudmila [28]

Notice that the 2 expressions have 2 common terms.

(r-s) is just (s-r) times (-1)

similarly

(t-s) is just (s-t) times (-1)

this means that :

(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)

the 2 minuses in the first multiplication cancel each other so we have:

-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)

Answer:

d)2(s-r) (t-s)
