A carpenter makes tools for electricians with square of pf side 0.5m and at a height 1.5m above the ground. Also, each leg is inclined at an angle of 60degree to the ground. Find lengh of each leg also the lenghs of steps to the at equal distances in metres correct up to two places of decimals. [Take root3 = 1.73].

Length of each leg can be calculated by using trigonometric ratios.
Height = 1.5
Angle between ground and the inclined leg(Hypt)= 60
Use sin 60 to find the hypt.
At the height for each step is 0.5 so 3 steps would be there of 0.5 m each

Use this number of steps being 3 to find the details of each step.
