In the triangle shown above m∠B = 114°, m∠C = 22°, and b = 12 in. What is the approximate length of side a? A. 15.78 in B. 9.12
Elena L [17]

The approximate length of side a is 9.12 in. The correct option is B. 9.12 in

<h3>Law of Sines </h3>

From the question, we are to determine the approximate length of side a

From the given information, we have that

m∠B = 114°, m∠C = 22°

Thus,

m∠A = 180° - (114° + 22°)

m∠A = 180° - 136°

m∠A = 44°

Now,

From the law of sines, we have that

a/sinA = b/sinB

Then,

a/sin44° = 12/sin114°

a = (12 ×sin44°)/sin114°

a = 9.12 in

Hence, the approximate length of side a is 9.12 in. The correct option is B. 9.12 in

You buy items totaling $135.82. The sales tax is 4%. You give the clerk three $50 bills. Figure the following amounts:
MrRa [10]

Answer:

a. $5.43

b. $141.25

c. $8.75

Step-by-step explanation:

First you find the total amount you it cost for all the items

$135.82 + 4% = $141.25

You give three $50 dollar bills

50 * 3 = 150

$150 is the amount you give

--------------------------------------

141.25 - 135.82 = 5.43

$5.43 is the amount of the sale price

---------------------------------------

To find the amount is cost for all the items you add the sales tax + the original price

$135.82 + 4% = $141.25

$141.25 is the amount including the tax

---------------------------------------

Subtract

150 - 141.25 = 8.75

So you will get $8.75 back
