Step-by-step explanation:
Answer:
W=16 2/3
L=28 1/3
Step-by-step explanation:
L=2W-5
80=2W+2L
80=2W+2(2W-5)
80=2W+4W-20
80=6W-20
100=6W
W=16 2/3
L=2(16 2/3)-5
L=33 1/3 -5
L=28 1/3
Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27

Find angle y first by setting it equal to 180
With its adjacent angles. Then solve for x by triangle angles
