Answer:
<h2>40</h2>
Step-by-step explanation:
90 degree angle
90 - 50 = 40
The length is 18 and it's width is 10 because 10+8=18 and 18•10=180
LW=105
L+W=26
L=26-W
(26-W)W=105
26W-W^2=105
0=W^2-26W+105
-105=W^2-26W
-105+169=W^2-26W+169
64= (W-13)^2
8= -(W-13) and (W-13)
8= -W+13
5=W
8= W-13
21=W
105= 5*21
Answer: 5 feet x 21 feet
