Use this triangle.

1 answer:

5 0

The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse

so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.

b ) sin 45 = 1 / sqrt2 = sqrt2 / 2

c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2

Jar contains 200 old dimes

Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes

So, we can write

$\Rightarrow \text{No of 1960s is }=20\%\ \text{of}\ 200=0.2\times 200\\\Rightarrow \text{No of 1960s is }=40$
