Answer:
4
Step-by-step explanation:
The diagonals are equal length:


The angle to the left of angle 1 is 70, so angle 1 is equal to 180 - 70 - 70 which is 40,
233 1/3
you start with .3x = 70, as this is the sentence given, solving for x.
divide both sides by .3, and you get x
Answer:
- f−1=log3x. Explanation: y=3x ⇒log3y=log3(3x) (logarithms of both side are equal) ⇒x=log3y ⇒f−1=log3x.Step-by-step explanation:
