What is the sum of the measures of the exterior angles of this triangle?
fgiga [73]

Answer:

360°

Step-by-step explanation:

We need only remember that the sum of the measures of the interior angles of a triangle is 180°.  Angle c and 112° form a pair of "straight angles," so they add up to 180°; as a consequence, Angle c = 180° - 112°, or 68°.

With two of the interior angles now known, we can calculate the third, Angle A:  It is 180° less (51° +  68°), or 180° - 119°, or 61°.

That means that the measure of Angle B is 180° - 61° = 119°

Looking at the pair C and 112°, we identify the exterior angle as 112°.

Looking at the pair A and B, or 61° and 119°, we identify the exterior angle as 119°.

Finally, looking at the pair 51° and (180° - 51°), or

51° and 129°, we identify the exterior angle as 129°.

Then the sum of the exterior angles 129° and 119° and 112° is 360°.

An electronics store has portable CD players on sale for $54.95. If the local sales tax is 6.5%, what is the total cost of a CD
borishaifa [10]

Answer:

Total cost of CD player = $58.52

Step-by-step explanation:

Given data:

Price of CD player on sale= $54.95

Local sales tax = 6.5%

Total cost of CD player = ?

Solution:

Local sales tax= (6.5 * 54.95)/100 = $3.57

Total cost of CD player = Price of CD player on sale + Local sales tax

                                       =  $54.95 + $3.57

         Total cost of CD player = $58.52
