lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

\frac{1+Cos2x}{Sin2x}

We have to verify the identity.

We know that

1+Cos2x=2Cos^2 x

Sin2x=2SinxCos x

Using the formula

\frac{2Cos^2x}{2SinxCosx}

\frac{Cosx}{Sinx}

Cot x

By using the formula

Cotx=\frac{Cosx}{Sinx}

LHS=RHS

Hence, verified

Rzqust [24]
To find a percent of a number, multiply the percent by the number.

First we find the number of pennies.

40% of 220 =

= 40% * 220

= 0.4 * 220

= 88

88 coins are pennies.

220 - 88 = 132

132 coins are not pennies.

Now we find 25% of 132.

25% of 132 =

= 25% * 132

= 0.25 * 132

= 33

33 coins are partners.

(Did you mean quarters instead of partners?)
