PL HEL!!! a new parka with a manufacturer's price of $220 was marked up 120% but was sold at a discount of 40% at the end of the season. If 15% sales tax was added to this cost, then the total price paid by the customer was...

tip $2.90

total $17.40

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
