Answer:
Explanation:
6) ∆ ABC is similar to ∆ CDE. This means that
Angle B = angle D
Therefore,
8x + 16 = 120
Subtracting 16 from the left hand side and the right hand side of the equation, it becomes
8x + 16 - 16 = 120 - 16
8x = 104
Dividing the left hand side and the right hand side of the equation by 8, it becomes
8x/8 = 104/8
x = 13
7) ∆ ABC is similar to ∆ XYZ. It means that
AB/XY = BC/YZ = AC/XZ
Therefore
11/22 = AC/32
22AC = 32 × 11 = 352
AC = 352/22 = 16
The factor is 2
Therefore,
BC = 44/2 = 22
Perimeter of ∆ABC = 22 + 16 + 11 = 49
