Marsha is buying a new cell phone. She has a 45% off coupon from the store. She pays $275 for the cell phone. What is the price
jekas [21]

Answer:

The price of the cell phone without the coupon= $500

Step-by-step explanation:

Step 1: Express discounted amount

The discounted amount can be expressed as a function of the original  cost of the phone as follows;

D=r×A

where;

D=discounted amount

r=coupon rate

A=original price of the cell phone before the coupon

In our case;

r=45%=45/100=0.45

A=a

replacing;

Discounted amount=(0.45×a)=0.45 a

Step 2: Amount she pays up

Amount she pays=Original cost of cell phone-discounted amount

where;

Amount she pays= $275

original cost of cell phone=a

discounted amount=0.45 a

replacing;

$275=a-0.45 a

0.55 a=275

a=275/0.55

a=500

The price of the cell phone without the coupon= $500

In triangle abc, ac=12, the measure of angle a = 30\deg, and the measure of angle b = 45\deg. find the area of this triangle.
Anuta_ua [19.1K]

First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.

So we will get

C = 180-30-45 = 105 degree

Now we use sine law, which is

\frac{sin \ A}{BC} = \frac{sin \ B }{AC}

Substituting the values, we will get

\frac{sin 30}{BC} = \frac{sin 45}{12}

BC = \frac{12 sin 30}{sin 45} = 6 \sqrt2

The formula of area of triangle, for the given triangle is

Area= \frac{1}{2}AC*BC sinC

Area = \frac{1}{2}*12*6 \sqrt 2 sin(105)= 49.2 \ square \ units
