-- DEC is a right triangle.
-- DC is one side of the square = 10 cm
-- EC is half the side of the square = 5 cm
-- DE is the hypotenuse = square root of (5² + 10²) = √(125 cm²) .
<em>-- Truncated</em> to one decimal place, that's 11.1 cm.
<em>-- Rounded</em> to one decimal place, it's 11.2 cm.
In 1st month let she exercised h hours
in second month she exercised h+4 hours
in third month she exercised h+4-3=h+1 hours
Now
- h+h+4+h+1=101
- 3h+5=101
- 3h=96
- h=32hours
<span>m∠CED = </span><span>1/2(m∠AOB + </span><span><span>m∠COD)</span> = 1/2(90° + 16°) = 1/2(106°) = 53°</span>
