The photograph shows the arm of a mechanical digger. It is controlled by three hydraulic pistons called 'rams', labelled X, Y and Z.
Explain why the arm is raised when compressed air is released into ram X so it extends.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

just pick what you think i need more time let me know if this
