Answer: I believe it is 1.1x10^-8

Step-by-step explanation:

Because 3.4x10^2 divided by 3x10^10 gives you 0.00000011 which is then converted through scientific notation into 1.1 x10^-8

Literally 50 points for whoever can answer this
Liula [17]

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°

Math help please? &lt;3
Digiron [165]
Point-slope form is :  y-y₁=m(x-x₁)

The points given are : (8, -4)

Slope given : -5/6

So, simply plug in the values.

Remember, m = slope

y - y₁ = m(x - x₁)

y - (-4) = -5/6(x - 8)

Simplify.

y + 4 = -5/6(x - 8)

So, your answer is the THIRD choice.

~Hope I helped!~
