Find the measure of each interior angle

Mathematics

arsen [322]2 years ago
8 0

Answer:

∠J = 115

∠N  = 65

∠M = 50

∠K = 130

Step-by-step explanation:

Sum of all the angles = 360

2x + 15 + x + 15 +x + 3x - 20 = 360

Combine like terms

2x + x + x + 3x + 15 + 15 - 20 = 360

               7x + 10 = 360

                      7x  = 360 - 10

                     7x = 350

                     x = 350/7

x = 50

∠J = 2x + 15 = 2*50 + 15 = 100+15 = 115

∠N = x +15 = 50 +15 = 65

∠M = x = 50

∠K = 3x - 20 = 3*50 - 20 = 150 - 20 = 130

The list price of a refrigerator is $1899. The chain discount is 20/15. What is the final net price?
shusha [124]
1st = 100% - 20% = 80%
2nd= 100%-15% = 85%

Net Price Factor = 0.8 x 0.85 = 0.68

Net Price = $1899 x 0.68

Final Net Price = $1,291.32

Total Discount= $1899 - 1,291.32 = $607.68

What is the sum of the arithmetic sequence 151, 137, 123,..if there are 26 terms?
ElenaW [278]
First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)

nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165

This will be used in the formula below

Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624

The final answer here is choice C) -624
