Answer:

see explanation

Step-by-step explanation:

Complementary angles sum to 90°, thus

∠A ∠B = 90 ← substitute values

5x - 27 + 4x - 27 = 90, that is

9x - 54 = 90 ( add 54 to both sides )

9x = 144 ( divide both sides by 9 )

x = 16

Hence

∠A = 5x - 27 = (5 × 16) - 27 = 80 - 27 = 53°

∠B = 4x - 27 = (4 × 16) - 27 = 64 - 27 = 37°

John is adding a curved edge to the landscaping in front of the high school. The curve is an arc of a circle with a radius of 16
8090 [49]
By definition, the arc length is given by:
 S = R * theta
 Where,
 Theta: central angle
 R: radio
 Substituting the values we have:
 S = (1600) * (π / 8)
 Rewriting we have:
 S = 200π feet
 S = 628.3185307 feet
 Round to the nearest foot:
 S = 628 feet
 Answer:
 
The length of the curve to the nearest foot is 628 feet.

Answer:

Step-by-step explanation:

Rise over Run is what Slope is. So basically we look at it and go how do we get from -6 to -3? Well you add 3, so thats your top number. We look at the bottom of the fractions now. We use the same thought process. How do you get from 14 to 9? Subtract 5. So our slope is 3/-5. Hope this helps
