A 96 foot tree casts a shadow that is 120 feet long. What is the angle of elevation of the sun? Round to the nearest degree.
zysi [14]

Answer:

\alpha \approx 39^{\circ}

Step-by-step explanation:

Let assume that tree grows perpendicular to surface. The statement is geometrically represented in the attachment included below, which resembles a right-angled triangle. Lastly, the angle of elevation of the sun is determined with the help of the following trigonometric relationship:

\tan \alpha = \frac{96\,ft}{120\,ft}

\tan \alpha = \frac{4}{5}

\alpha = \tan^{-1}\left(\frac{4}{5} \right)

\alpha \approx 38.660^{\circ}

\alpha \approx 39^{\circ}

5. Twenty-five sixth-grade students entered a math contest consisting of 20 questions. The student who
Grace [21]

Answer:

two coins are flipped:

  • if dime land heads and nickel land heads then Allan wins
  • if dime land heads and nickel land tail then Beth wins
  • if dime land tail and nickel land heads then Carlos wins
  • if dime land tail and nickel land tail then Denesha wins

Step-by-step explanation:

The method described above is fair since the probability of each case is 0.25.

If the two coins are flipped:

  • The probability dime land head is 0.5
  • The probability dime land tail is 0.5
  • The probability nickel land head is 0.5
  • The probability nickel land tail is 0.5

Then the probability dime land heads and nickel land heads is 0.5 × 0.5 = 0.25.

The other four cases are calculated similarly and their probability is also 0.25

Prove that ΔABC and ΔEDC are similar.
Lesechka [4]

Answer:

∠DCE is congruent to ∠CBA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SSS Similarity Postulate.
