Hey there!

Notice in the image, <em>I</em> is in between Q and C and QC is made up of QI and IC.
Knowing this, you can conclude that QI+IC=QC

Since you know that QI=3x-13 and IC=2x-12, you can add these two expressions together to get QC:
(3x-13)+(2x-12)
5x-25

Therefore, QC is 5x-25.

UNO [17]

use SOHCAHTOA 

S = sine

O = opposite edge

H = hypotenuse

T = Tangent

A = adjacent edge

C = cosine.

The extreme is where the runaway is indicated by the hypotenuse is the required distance. Therefore,

sine 7= 3/H

H = 3/sine 7= 24mi
