8 0

Answer:

A and D are the answer.

Step-by-step explanation:

We can factor this by grouping

2 {x}^{2}  + 5x - 3

2 {x}^{2}   + 6x - x - 3

2x(x + 3) -1 (x + 3)

The roots are

(x + 3) = 0

and

2x - 1 = 0

Let solve for zero in each roots.

x =  - 3

2x = 1

x =  \frac{1}{2}

Two towers face each other separated by a distance = 15 m. As seen from the top of the first tower, the angle of depression of t
Crazy boy [7]

Answer:

Height of second tower = 17.32m

Step-by-step explanation:

I have attached a diagram depicting the question.

From the diagram, The first tower is depicted by side AEB and the second tower CD.

While d is the distance that separates the two towers and it's given as 15m.

Now, since the angle of depression of the second tower’s base is 60°, then for triangle BAC. Angle C = 60°.

Thus; using trigonometric ratios;

tan 60° = AB/AC.

This gives; AB = d*tan 60°

Similarly, for the triangle BED, BE = d*tan 30°

Since, AE = CD, thus ;

CD = AB − BE

CD = d (tan 60° − tan 30°)

CD = 15(1.7321 − 0.5774)

CD = 15 × 1.1547

CD ≈ 17.32 m.

So, height of second tower = 17.32 m
