<span>Since lines a and b are parallel and that m∠4 = 128°, therefore:
m<7 would be:
m<7 = 180 - m<4 = 180 - 128 = 52 degrees
Therefore, the measure of angle 4 would be 52 degrees.
I hope my answer has come to your help. God bless and have a nice day ahead!

Tourism is the LARGEST industry in the world.
Modern, human-caused climate change is escalating the threats that make sea walls necessary. Sea levels are rising, putting communities at greater risk from floods. Storms are intensifying, causing more and more sand to erode from beaches.
<h2>Answer: D. Rayleigh wave
</h2>
Rayleigh waves are a type of surface acoustic wave that causes particles on the surface of solids to travel along an elliptical path in the vertical plane that contains the direction of wave propagation.
These waves include longitudinal (P wave) and transverse (S wave) movements whose amplitude decreases exponentially as the distance from the surface increases.
This means Rayleigh waves are generated by the interference between the P and S waves on the surface of the Earth.
