Modeling the travel path of seismic waves by major earthquakes.
Answer:
1. x = 7.25
2. x = 36
Explanation:
1. Base on intersecting secants theorem, therefore:
DE × DF = DG × DH
DE = 11
DF = 11 + 10 = 21
DG = 12
DH = 12 + x
Therefore,
11*21 = 12(12 + x)
231 = 144 + 12x
231 - 144 = 12x
87 = 12x
Divide both sides by 12
x = 7.25
2. Based on the secant-tangent rule, we have:
CD*CA = CB²
CD = 12
CA = 12 + x
CB = 24
Thus:
12(12 + x) = 24²
144 + 12x = 576
12x = 576 - 144
12x = 432
Divide both sides by 12
x = 432/12
x = 36
The correct answer is letter C.
<span>Mountains form when collisions of two continental
plates with the same density occur. It is a major phenomenon of the Earth’s
plate tectonics and it occurs at the Earth’s convergent boundaries. During this
occurrence, subduction zones are destroyed, mountains begin to form, and the
two continents merge together. </span>
