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.
Answer:
70.47feet
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE INTERPRETATION OF THE QUESTION USING A FIQURE
From the attachment we can see that a triangle was formed, where the
OPPOSITE SIDE= X
HYPOTENUSE=76feet
From trigonometry,
Sin(θ)=opposite/Hypotenuse
Sin(68)= X/76
Cross multiply, we have,
X= Sin(68) × 76
X= 0.9272 × 76
X= 70.47feet
Therefore, the antenna is 70.47feet tall.
