Answer:
x = 10
Explanation:
Based on the theorem of angles formed by two intersecting chords, thus:
Angle formed/vertex angle = ½(sum of intercepted arcs)
Angle formed/vertex angle = 60°
Sum of intercepted arcs = 55 + 5x + 15 = 5x + 70
Therefore:
60 = ½(5x + 70)
Multiply both sides by 2
60*2 = 5x + 70
120 = 5x + 70
120 - 70 = 5x
50 = 5x
Divide both sides by 5
50/5 = x
10 = x
x = 10

Explanation:
the answer is TRUE. I just took the test
Igneous Rocks
At diverging plate boundaries, convection currents bring hot magma to the surface. Sometimes, magma that gets pushed up at plate boundaries cools before it gets there. It fills in cracks and voids in the bedrock
Metamorphic Rocks
Hot magma pushes itself to the surface at both divergent plate boundaries and convergent plate boundaries. This magma comes in contact with rocks as it rises to the surface.
