Answer:
Answers all found below.
Step-by-step explanation:
1) Given from diagram, RT = RS + RT
RT = 2cm + 2.5cm = 4.5cm
2) Given from diagram, AC = AB + BC
BC = AC - AB
= [tex]6 in-2\frac{3}{4} in\\=3\frac{1}{4} or 3.25in[/tex]
3)Given from diagram, XZ = XY + YZ
XZ = [tex]3\frac{1}{2} +\frac{3}{4} \\=4\frac{1}{4} or 4.25in[/tex]
4)Given from diagram, WX = XY and WY = 6cm
WX = WY / 2
= 6 / 2
= 3cm
For Questions 5,6 and 7, refer to the attached photos, apologies for the terrible drawing.
5) From the diagram,
RS + ST = RT
5x + 3x = 48
8x = 48
x = 48 / 8
= 6
6) From the diagram,
RS + ST = RT
2x + 5x+4 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
x = 28 / 7
= 4
7) From the diagram,
RS + ST = RT
6x + 12 = 72
6x = 72 - 12
6x = 60
x = 60 / 6
= 10
