Step-by-step explanation:

(3x² / 2 )° = 96° [ being corresponding angles ]

3x² = 192°

x² = 192/3

x² = 64

x² = (+ 8) ²

Therefore x = +8 and -8

Hope it helps. :)

yes

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
