Answer:
Minor earthquakes occurred in the country in the last year were<u> 2326</u>.
Step-by-step explanation:
Given:
In the last year, a total of 2727 earthquakes occurred in the country.
Of these, 85.3 % were minor tremors with magnitudes of 3.9 or less on the Richter scale.
Now, to find the minor earthquakes occured in the country last year.
<em>Total earthquakes occurred in the country = 2727.</em>
<em>The percent of minor earthquakes = 85.3%</em>.
Now, to get the number of minor earthquakes:
85.3% of 2727.
<em>The number of minor earthquakes nearest whole number = 2326.</em>
Therefore, minor earthquakes occurred in the country in the last year were 2326.

Every triangle has 180 degrees.
So all three angles add to 180
<em><u>Equation</u></em>
60 + 80 + x + 51 = 180
<em><u>Solution</u></em>
Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.
191 + x = 180
Subtract 191 from both sides.
191 - 191 + x = 180 - 191
x = - 11

If a triangle is a right triangle and one of the angles is 45, then so is the other one.
<em><u>Proof</u></em>
a + 45 + 90 = 180 Combine like terms on the left
a + 135 = 180 Subtract 135 on both sides.
a + 135-135=180-135 Combine the like terms
a = 45
<em><u>Statement</u></em>
That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides
52 - 52 + x = 45 - 52 Combine like terms.
x = - 7
