Question

I really need help can u help me please ?

Answer 1

Answers all found below.

Explanation:

1) Given from diagram, RT = RS + RT

RT = 2cm + 2.5cm = 4.5cm

2) Given from diagram, AC = AB + BC

BC = AC - AB

=
`6 in-2(3)/(4) in\\=3(1)/(4) or 3.25in`

3)Given from diagram, XZ = XY + YZ

XZ =
`3(1)/(2) +(3)/(4) \\=4(1)/(4) or 4.25in`

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
