the correct description if she is incorrect.

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?

When the ball has traveled a distance of

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
