A man's initial salary is N540.00 a month and increases after each period of six months by N36.00 a month. Find his salary in the eight month of the third year.
Give that the salary increases by 36 after every 6 months

Users' Answers & CommentsIn the figure shown, /MX/ = 8cm, /XN/ = 12cm, /NZ/ = 4cm and ∠ XMN = ∠ XZY. Calculate /YM/
From the figure,
∠ XMN = ∠ XZY
Angle X is common
So, ∠ XNM = ∠ XYZ
Then from the angle relationship
XM = 8, XZ = 12 + 4 = 16,
XN = 12, XY = 8 + YM
Cross multiply
8(8 + YM) = 192
64 + 8YM = 192
8YM = 128
YM =
= 16cm
