Last week, Donnell practiced the piano 3 hours longer than Marcus. Together, Marcus and Donnell practiced the piano for 11 hours
solong [7]

Answer:

4 hours and 7 hours

Step-by-step explanation:

Marcus = x hours

Donnell = x + 3 hours

Total = 11 hours

  • x + x + 3 = 11
  • 2x + 3 = 11

From a point 80m from the base of a tower, the angle of elevation to the top of the tower is 28 degrees how tall is the tower
Nadusha1986 [10]

The height of the tower is 42.54 m.

Solution:

The reference image of the answer is attached below.

Given data:

BC = 80 m, ∠C = 28°

$\tan\theta = \frac{\text{Opposite}}{\text{Adjacent}}

$\tan28^\circ = \frac{AB}{BC}

$\tan28^\circ = \frac{h}{80}

$0.5317 = \frac{h}{80}

Multiply by 80 on both sides, we get

42.536 = h

Switch the sides.

h = 42.536

h = 42.54 m

The height of the tower is 42.54 m.
