From the attached figure, AB is the height of the satellite and the distance between Ethan and the ground is 1 mile.
We can find the angle of elevation from Ethan to the satellite using trigonometry as follows :
So, the angle of elevation is 80.53 degrees.
Answer:
Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A =
∠B =
∠C =
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒
⇒
∴ ∠C = °
Now, the sum of all the interior angles of a triangle is always 180°.
Therefore, the value of 'y' is 5.
