Answer:
2.8
Step-by-step explanation:
tan = opposite / adjacent
( opposite = side opposite of the angle and adjacent = side length that is not the opposite nor the hypotenuse ( longest side ) )
we are given an angle, ∠E = 26°
tanE = x / 5.7
tan26 = x / 5.7
==> multiply both sides by 5.7
5.7tan26 = x
==> simplify
x = 2.8 ( rounded )

Answer:
-1
Step-by-step explanation:
A polynomial doesn't include no negative exponents so our answer has to be negative in order to make our power positive.
This terms is in between a quadratic and constant term so the terms has to be raised to 1st power.
It has to be negative so the answer will be
-1
So if we do not know what 12 times 9 is then we can round 9 to 10 and get
12 times 10
most people can multiply by ten so this should be easy so
12 times 10=120
12 times 9=108
she was off by 12 so a 10% deviation error
another way to do it is you multiply 12 by 10 and get 10 12's
then you subtract 1 12 and get 9 12's
