We can solve the length of u using Laws of Cosine since we are given with lengths of two side and one angle.
The solution is shown below:
cos U =( s²+t²-u²)/2st
cos 37°= (9²+15²-u²)/2*9*15
0.79863*270=306-u²
u²=306-215.63
u=9.5 units
Therefore, the length of u is 9.5cm.

A pet store has 80 geckos and anole lizards altogether.

larisa86 [58]

I don’t know what your trying to find but you basically create an equation, like this
3x+5x=80
and solve which would result in x=10
so there is
30 geckos
and
50 anole lizards

For F (x) =3x+5 Evaluate f (0)

Slav-nsk [51]

F(0)= 5 because 3(0) is the same as 0 and you add 5 so f(0)= 5
