A surveyor measures the distance across a straight river by the following method: Starting directly across from a tree on the opposite bank, he walks x = 108 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is θ = 37.4°. How wide is the river?

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

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
