Answer: 75.96^{\circ}.

Step-by-step explanation:

By considering the given information we draw a picture to represent the situation ( given in attachment)

Since the tower stands vertical to the ground , therefore , the triangle is a right triangle.

Let x be the angle of elevation from a point 50 feet from the base of the tower to the top of tower.

According to the trigonometry , the tangent of an angle is the ratio of "the side opposite to angle" to "the side adjacent to the angle".

For the triangle below , \tan x=\dfrac{200}{50}=4\\\\ x=\tan^{-1}(4)=1.32581766\ radians\ [\text{By scientific calculator}]\\\\=1.32581766\times\dfrac{180^{\circ}}{\pi}\ \\\\=75.9637563^{\circ}=75.96^{\circ}

[Note:To convert radians into degrees we multiply it by 180^{\circ}} and divide it by\pi]

Hence, the angle of elevation from a point 50 feet from the base of the tower to the top of tower is 75.96^{\circ}.

-30=5(x+1)−30=5(x+1) proszę szybką odpowiedź :)
den301095 [7]

Answer:

x = -7

Step-by-step explanation:

The given equation is :

-30=5(x+1)

We need to solve the equation.

Use associative property on RHS.

-30 = 5x+5

Subtract 5 from both the sides.

-30-5 = 5x+5-5

-35 = 5x

x = -7

Hence, the value of x is -7.
