Liula [17]2 years ago

Answer:

  • 92°

Step-by-step explanation:

<u>Sum of internal angles of a regular polygon is:</u>

  • S = 180(n - 2)

<u>We have here 5-sided polygon:</u>

  • S = 180*(5 - 2) = 180°*3 = 540°

<u>Now sum the given angles measures and solve for x:</u>

  • 3x + 1 + 2x + 15 + 3x - 10 + 3x - 8 + 5x - 2 = 540
  • 16x - 4 = 540
  • 16x = 544
  • x = 544/16
  • x = 34°

<u>Find the measure of angle R:</u>

  • m∠R = 3x - 10 = 3*34 - 10 = 102 - 10 = 92
  • m∠R = 92°

6 The length of the side of a square is (x + 6).
Brums [2.3K]

Answer:

x^2 ×1 2x + 36

Step-by-step explanation:

area of a square = L × B

= (x+6) (x+6) since a square has 4 equal sides, it becomes (x+6) (x+6)

= x(x+6) +6(x+6)

= x^2 + 6x + 6x +36

= x^2 + 12x +36 added all the like terms 6x + 6x = 12x

hope this helps ☆☆☆

HELP MEEE PLS recipe cslls for 2 cups of suger and makes 48 cookies recipe B calls for 3 cups of suger and makes 54 of the same
JulijaS [17]

Answer:

So, when we solve for x we see that we can make 16 cookies using 1 cup of sugar. Then, yes, as you suggested we could divide 30 cookies by this ratio to see that we need less than 2 cups of sugar to make 30 cookies: And, as you said, this value is less than 2 cups, the value under Quantity B. Good job! I hope this helps :)

What number is 15% of 80?<br> use percent proportions
vova2212 [387]
!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100. 

Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.

x/80 = 15/100
x = (15/100)*80
x = 12

Thus, the 15% of 80 is 12.
