D.

Tan is opposite/adjacent
Tan35 = .7002
.7002 = opposite/60
.7002*60=42.012
Opposite = width of river = 42.0

Luda [366]

Answer:

46°

Step-by-step explanation:

Since the 3 sides are given we can use any of the 3 trig. ratios to solve.

Using the tangent ratio in the right triangle

tan ? = \frac{opposie}{adjacent} = \frac{42}{40}, thus

? = tan^{-1} (\frac{42}{40} ) ≈ 46° ( to the nearest degree )

A subway train is traveling at a rate of 22.4 m/s. Brakes are applied and it slows down at a constant rate of 3.5 m/s2 until it
WARRIOR [948]

You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.

Happy Paws charges $20.00 plus $5.50 per hour to keep a dog during the day. Woof Watchers charges $9.00 plus $6.75 per hour. Com
marta [7]

Answer:

8.8 hours

Step-by-step explanation:

Happy paws cost equation

5.50h + 20

Wood watchers cost equation

6.75h + 9

Make the two equations equal

5.50h+20 = 6.75h+ 9

Collect the co-efficient of both sides.

6.75h- 5.50h= 20-9

1.25h= 11

Divide both sides by the coefficient of h

1.25h/1.25= 11/1.25

h= 8.8

The figure below is from a quilting pattern. The indicated angles are Supplementary. What is the news he or N and the two angles
VashaNatasha [74]

Answer:

  • <u>The value of N is 8</u>

<u></u>

  • <u>The value of the angles is 48º</u>

Explanation:

The two indicated angles are supplementary because they could be drawn as two interior angles on the same side of two parallel sides cut by a transversal.

Thus, those measure of those two angles add up 180º, which lets you to write an equation and solve for N:

  • 8N - 16 = 6N
  • 8N - 6N = 16
  • 2N = 16
  • N = 16 / 2
  • N = 8

And the value of the angles is:

  • 8N - 16 = 8(8) - 16 = 48, or
  • 6N = 6(8) = 48
