Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a

If a plane travels 13 miles in one minute, in an hour, it will have traveled 780 miles. The trips the plane takes are 768 miles, and the plane takes the trip six times. multiply the miles of the trip by the amount of trips. 768 x 6 = 4,608. It will take 5 - 5 1/2 hours to make the trips.

Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log
