Please help. Ill give brainliest. What explains how the Hawaiian Islands formed as a chain?
The Hawaiian Islands were formed by tectonic uplifting of the Pacific plate.
The Hawaiian hotspot moved under the Pacific plate exuding lava that created a chain of islands.
Volcanic hotspots appear spontaneously along the Pacific plate exuding lava that created a chain of islands.
The Pacific plate moves over a stationary hotspot exuding lava that created a chain of islands.

The Pacific plate moves over a stationary hotspot exuding lava that created a chain of islands.

Step-by-step explanation:

The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
