Answer:
17
Step-by-step explanation:
Let the two "middle" vertexes be x1 and x2, and let the "lower" vertex be y. We know that
Therefore x1=x2. We'll call that value just x.
But now we have to be careful, because
Simplifying we can get the value of x:
Now, substituting back in, we get
So, the sum of all vertexes is equal to
Answer:
10.99 m
Step-by-step explanation:
✍️What we are basically asked to solve here is to find the distance between C and D.
To find CD, find the length of BC, and BD. Their difference will give us CD.
Thus, BC - BD = CD.
✍️Finding BC using trigonometric ratio formula:
Opposite side = BC = ??
Adjacent side = 42 m
Thus:
Plug in the values
Multiply both sides by 42
BC = 35.24 m
✍️Finding BD using trigonometric ratio formula:
Opposite side = BD = ??
Adjacent side = 42 m
Thus:
Plug in the values
Multiply both sides by 42
BD = 24.25 m
✍️How much below the top of the tower is the shorter one attached:
Thus,
BC - BD = CD
35.24 m - 24.25 m = 10.99 m
