Emerson practice a game that was on sale for 18% off the sales tax in his country is a present let y represent the original pric
lawyer [7]

Answer: y - 0.18y

Step-by-step explanation:

From the question, Emerson practice a game that was on sale for 18% off the sales tax in his country.

Let y represent the original price of the game. The be used to determine the final cost of the game will be:

We have to subtract the 18% discount from the original price to get the final cost of the game. This will be:

= y - (18% of y)

= y - (18/100 × y)

= y - (0.18 × y)

= y - 0.18y

The final expression is y-0.18y

In triangle ABC, a = 9, c = 5, and angle B = 120°. Find the measure of angle A to the nearest degree. Show your work.
slamgirl [31]

<u>Answer:</u>

Angle A = 39°

<u>Step-by-step explanation:</u>

We are given that there is a triangle ABC where a = 9, c = 5 and angle B = 120° and we are to find the measure of angle A.

But first we need to find the side b using the law of cosine:

b^2 = a^2 + c^2- 2a*c*cos(120)

b^2 = 81 + 25 - 2*9*5*(-0.5)

b=\sqrt{151}

Now finding angle A using law of cosine:

cos(A) = \frac{b^2+c^2-a^2}{2b*c}

cos(A) = \frac{151+25-81}{2*12.29*5}

cos A=0.7730

A=39.38

Therefore, the measure of angle A = 39°.
