Answer:

The Height of the cliff is 41.5 meters tall.

Option B. 41.5 meters.

Step-by-step explanation:

Given:

AB = 85 meter

Angle of elevation ∠ C= 26°

To Find:

Cliff height = AB = ?

Solution:

In right angle Triangle ABC by tangent Identity we have

$\tan C = \frac{\textrm{side opposite to angle C}}{\textrm{side adjacent to angle C}}$

Substituting the given values we get

$\tan 26 = \frac{AB}{BC}=\frac{AB}{85}$

$\therefore AB=85\times 0.4877=41.45=41.5\ meters$

The Height of the cliff is 41.5 meters tall.

Fin the values of x and y, help me

astraxan [27]

Answer:

x = 25 , y = 19

Step-by-step explanation:

Since the triangle has 3 congruent sides then it is equilateral

The 3 angles are also congruent, with each angle = 60° , then

2x + 10 = 60 ( subtract 10 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

and

3y + 3 = 60 ( subtract 3 from both sides )

3y = 57 ( divide both sides by 3 )

y = 19
