Answer:

In geology, a hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time.

Many of the world's volcanoes occur along the plate margins (e.g. Pacific Rim of Fire), but some occur wholly in isolated pockets within plates (e.g. Yellowstone National Park in the USA). The latter form from hotspots of upwelling magma that pierce the crust, forming voluminous volcanic outpourings

one angle of a triangle measures 125 degrees the other two angles are in a ratio of 4:7. what are the measures of the two angles

Ilya [14]

Angles in a triangle add up to 180 degrees.
180 - 125 = 55
Add the ratios 4+7 = 11
Divide the left over angels by the ratio: 55/11 = 5
Now multiply 5 by each side of the ratio:
4:7
4*5 = 20
7*5 = 35

So the 2 angles are 20 and 35 degrees.

To check, you can add up all the angels : 20 + 35 + 125 = 180
So we know 20 and 35 is correct because it adds up to 180 degrees :)
