Answer:
Step-by-step explanation:
in a right angled triangle angles given are 45,90
Then third angle is also 45 °
as two angles are 45° each.
Then sides are also equal.
Let the equal sides be each =x
then hypotenuse=√(x²+x²)=√(2x²)=x√2
sin 45°=x/(x√2)=1/√2
This is just multiplying not simplify.
he is fifty years old
six years ago he would have been 44 yearsold
2m 10cm = 210cm
Perimeter = 2(length+width)
P = 2(210+45)
P = 2(255) cm
P=450 cm
Therefore, the rectangle's perimeter is 450 cm.
