The question is missing important data. The quadrilateral having vertices A, B, C and D is a cyclic quadrilateral.
Answer:
B) 85°
Step-by-step explanation:
Given:
A cyclic quadrilateral with ∠A is 95° and ∠B is 105°.
For a cyclic quadrilateral, the sum of the opposite interior angles is equal to 180°
Therefore, sum of angles A and C is 180°.
Therefore, the correct option is option B) 85°
The height of the tower is 42.54 m.
Solution:
The reference image of the answer is attached below.
Given data:
BC = 80 m, ∠C = 28°
Multiply by 80 on both sides, we get
42.536 = h
Switch the sides.
h = 42.536
h = 42.54 m
The height of the tower is 42.54 m.
