∠C is common in both triangles

equate them

∠C = 180- (x + 100) = 180 - ( 4x + 49)

x + 100 = 4x + 49

the area of a rectangle is 256.5 meters squared if the length is 18 meters what is the perimeter of the rectangle
PolarNik [594]
You would do 256.5/18 to get the other side which is 14.25, then you add 18 and 14.25 getting 32.25, now multiply that by 2 because there are 2 of each length sides, and you get 64.5 meters as the perimeter
