Answer:
c = 55° and d = 125°
Explanation:
Given that,

We need to find the measure of angle c and angle d.
We know that the sum of angles of a triangle is 180 degrees. So,
a+b+c = 180
85+40+c = 180
125+c=180
c = 180-125
= 55°
Using exterior angle theorem,
d = a+b
d = 85+40
d = 125°
Hence, c = 55° and d = 125°

Answer:
Erosion
Explanation:
Building a house on a cliff is a very trick thing. The cliffs usually are not composed of hard rocks, but instead are usually composed of sedimentary rocks which are much softer and less stable on the long run. The cliffs are also exposed to heavy erosion, in the lower parts because of the waves, in the higher parts because of the winds. The erosion makes the cliffs slowly fall apart, and occasionally even crumble down, so a builder that would build a house on a cliff should be wary of all these things and construct the house where it is the safest for the long run.
Answer:
Over the last two centuries the dipole strength has been decreasing at a rate of about 6.3% per century. At this rate of decrease, the field would be negligible in about 1600 years. However, this strength is about average for the last 7 thousand years, and the current rate of change is not unusual.
