Solve for x. Round to the nearest tenth.

x = 103.5

Step-by-step explanation:

tan 12 = 22/x

Multiply each side by x

x * tan 12 = 22/ x*x

x tan 12 = 22

Divide each side by tan 12

x tan 12 / tan 12 = 22/ tan 12

x = 22 / tan 12

x = 103.5018624

Rounding to the nearest tenth

x = 103.5

b) the dogs need to shift their focus to human scent.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
