Answer:
DE=6
Step-by-step explanation:
DE+EF=DF
9x-12+x+10=18
10x-2=18
10x=18+2
x=20/2=10
DE=9x-12 ⇒ 9(2)-12=18-12=6
DE=6

Answer: 28.9 inches ; 15.7 inches
Step-by-step explanation:
Given that:
Width to height = 16 : 9
Hence,
Width = 16x ; height = 9x
Using Pythagoras, solve for the length of the diagonal = 32
32² = 16x² + 9x²
1024 = 256x² + 81x²
1024 = 337x²
x² = 1024 / 337
x² = 3.0385756
x = 1.7431510
Width = 16( 1.7431510) = 27.89 = 28.9
height = 9(1.7431510) = 15.688 = 15.7
