10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5
You have to multiply whats outside the parenthesis with everything that is inside, so
Multiplication of same bases we sum the exponents
Alternative B.
1/5 goes into 37 185 times:
37 / (1/5) = 37*(5/1)=185
Im positive its false because they dont add up
