Mathematics: The law of cosines for rst can be set up as 52 = 72 + 32 – 2(7)(3)cos(s). what could be true about rst? law of cosines: a2 = b2 + c2 – 2bccos(a) r = 5 and t = 7 r = 3 and t = 3 s = 7 and t = 5 s = 5 and t = 3

If she used rounding she would’ve gotten -25×10 equals -250...

we know that

the law of cosines is equal to

$a^{2} =b^{2} +c^{2}-2(b)(c)cos(A)$

In this problem for the triangle RST

we have

$5^{2} =7^{2} +3^{2}-2(7)(3)cos(S)$

s=5

r=7 or r=3

t=3 or t=7

the possibilities are

1) s=5

r=7

t=3

2) s=5

r=3

t=5

therefore

the answer is the option

s = 5 and t = 3
