Answer:

  • B. 630 ft

Step-by-step explanation:

<u>Given:</u>

  • Horizontal leg of the right triangle = 778 ft
  • Angle opposite to vertical length = 39°
  • Vertical leg = h

<u>Use tangent to solve for h:</u>

  • h/778 = tan 39°
  • h / 778 = 0.81
  • h = 0.81*778
  • h = 630.18

Correct choice is B

ANSWER:

On using trigonometric function, we get

tanΦ = p/b

tan39° = p/778

p = 778 × 0.81

p = 630ft rounded.

So, <u>Correct choice</u> - [B] 630 feet.

A number line goes from negative 5 to positive 5. Point D is at negative 4 and point E is at positive 5. A line is drawn from po
Ronch [10]

<em>Directed numbers</em> are numbers that have either a <u>positive</u> or <u>negative </u>sign, which can be shown on a <em>number line</em>. Therefore, point F is Fifteen-halves of line <em>segment</em> DE.

A <u>number line</u> is a system that can show the positions of <em>positive</em> or <em>negative</em> numbers. It has its <em>ends</em> ranging from <em>negative infinity</em> to <em>positive infinity</em>. Thus any <em>directed</em> number can be located on the line.

Directed numbers are numbers with either a <u>negative</u> or <u>positive </u>sign, which shows their direction with respect to the <em>number line.</em>

In the given question, the <u>distance</u> between points D and E is <em>9 units</em>. So that <em>dividing</em> 9 units in the ratio of 5 to 6, we have;

\frac{5}{6} x 9   = \frac{45}{6}

          = \frac{15}{2}

Therefore, the <em>location</em> of point F, which <u>partitions</u> the directed line segment from d to E into a 5:6 ratio is    \frac{15}{2}. Thus the<em> answer</em> is <u>Fifteen-halves.</u>
