brian gets x
alex gets 9x
colin gets 3x

Answer:
10 feet
Step-by-step explanation:
define variables:
y= height of the boards
x= distance to corner
we are trying to figure out what x is since we know the height of the board
4= 0.4x
divide both sides by 0.4
10=x
(1) QS bisecting <PQR implies <PQS = <SQR
(2) <PQS=45 deg and (1) imply <SQR also = 45 deg
(3) from (2) it follows that <PQR = <PQS + <SQR = 45 + 45 deg = 90 deg and therefore the triangle is right-angled
