Answer:
115°
Step-by-step explanation:
Knowing that the sum of all interior angles of any triangle is 180 degrees, we can find the measurement of the missing angle of the triangle. The calculation is 180 - 75 - 40 = 65. Then, notice that the blue angle and the missing angle are supplementary (linear; add up to 180 degrees). So we can find the blue angle's measurement by 180 - 65, so the answer is 115 degrees.

Step-by-step explanation:
The major advantage of exponential notation is that it simplifies a number into a more readable form, so we don't have to count all the zeros every time we look at it / calculate it. It helps us to identify big numbers as small decimals which we are more familiar with.

Step-by-step explanation:
Logarithmic scales are not linear, and they are used for large range of possitive numbers. The value represented by each equidistant mark on the scale is the value at the previous mark multiplied by a constant, in this case 10.
So, in large islands, large incresaes have a small effect ( the distance is the same from islands thas has 100 to 90 square miles, than for 2 islands measuring 10 to 9).
