Answer:
log₃(243) = x
Step-by-step explanation:
3^x = 243
Rule: a^x = b -> logₐ(b) = x
log₃(243) = x
Answer: 25
Step-by-step explanation:
Plug in x to the expression.

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to,
.
This then solves to 25.
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
