Answer: 44º

Step-by-step explanation:

Hi there! To start out, disregard Y and Z, as they are just there to trip you up.

Use the Triangle Sum Theorem to find out the question! This theory states that all angles in a triangle add up to 180 degrees. So, just set up an equation, like the one down below!

82+54+X=180

Then, add the whole numbers!

136+X=180

Then isolate X by using inverse operations!

136+X-136=180-136

Then your answer is there!

X=44

If you have any follow up questions, please let me know! Have a nice day

If you purchase a DVD player that cost $625 how much sales tax will you pay to the nearest cent if the rate is 7.375%

sergey [27]

We can get the tax pay by multiplying the total cost times the tax rate, and take into account that 7.375% = 7375/100000 that huge denominator comes from adding 100 more zeroes as the decimal places in the tax amount has, so we do have:
(7.375%)(625)
= (7375/100000)(625)
= 46.09
therefore, the 7.375% out of $625 is $46.09
