When gold medalist Ren Qian prepared for her dive from the 10 meter platform during the
Romashka-Z-Leto [24]

Answer:

Ren was 27.5 meters away from her family.

Step-by-step explanation:

Ren Qian was at a height of 10 meters to the ground. Let the distance from her vertical point on the ground to her family (i.e the ground distance) be represented by x.

But the angle of depression is measured with respect to the horizontal plane, so;

the vertical angle = 90^{o} - 20°

                             = 70^{o}

Applying the appropriate trigonometric function, we have;

Tan θ = \frac{opposite}{adjacent}

Tan 70^{o} = \frac{x}{10}

⇒ x = 10 x Tan 70^{o}

      = 10 x 2.7475

      = 27.475

x = 27.5 meters

Ren was 27.5 meters away from her family.

To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that
4x + 20 = 3x + 55
we can subtract twenty from each side
4x + (20 - 20) = 3x + (55 - 20)
4x = 3x + 35
now we can subtract like terms
4x - 3x = (3x - 3x) + 35
so we can get the final answer as
1x = 35

cos = \frac{adajcent}{hypotenuse}

cos P = \frac{24}{74}

cos P = 0.324
