Find the value of a and b

Mathematics
1 answer:
Luba_88 [7]2 years ago
3 0

Answer:

a = 60

b = 60

Step-by-step explanation:

We know that BC is 90°, because of the square thingy.

YB is 30°.

Now we do 180 - 30 - 90 = 60 (180 is the straight angle)

60  = b

Then a is the same.

How do logarithmic equations relate to exponential equations?

log_{2}(y) = x


By general definition:

y = b^x = log_{b} (y) = x
