Delvig [45]

Answer:

The angle of depression between the cliff and the boat is $48.8141^\circ$

Step-by-step explanation:

Given:

Base width of the cliff=175 foot

Height of the cliff= 200 foot= 200 foot

To Find:

The angle of depression between the cliff and the boat=?

Solution:

Angle of Depression

The angle below horizontal that an observer must look to see an object that is lower than the observer.The angle of depression is congruent to the angle of elevation

$tan( y )= \frac{opposite}{adjacent}$

Substituting the values,

$tan( y )= \frac{200}{175}$

$tan( y )= 1.14$

$y= tan^{-1}(1.14)$

$y=48.8141^\circ$

What is x?

Nadya [2.5K]

Answer:

Option 3) 24 is right.

Step-by-step explanation:

Given in the picture is a triangle LMN. sides are MN = 12, LN = 21 and LM = x cm

Also MO is the angle bisector of angle M.

By applying angle bisector theorem for triangles we get

LM/MN = LO/NO

i.e. x/12 = 14/7

Simplify to get x = 24

Hence option 3 is right

Verify:

Check whether angle bisector theorem is true.

The proportion LM/MN =24/12 = 2

The proportion LO/NO =14/7 =2

Both are equal and hence verified
