Answer:
Just to start you off the first answer is 66.67
Step-by-step explanation:
You divide the first number by the second number so in this case 800/12=66.67
Answer:
60 degrees
Step-by-step explanation:
because two inner angles equals the opposite side's outer angle, we can do this
3y + 13 + 4y = 118
we combine like terms
7y + 13 = 118
subtract
7y = 105
and then divide
y = 15
then we do the equation for A's angle
4(15) = 60
In terms of algebra, writing "am" is the same as writing "a*m" or "a times m"
To undo the multiplication, we use division. We will divide both sides by m to get 'a' all by itself on the left side
So...
am = n+p
a*m = n+p
(a*m)/m = (n+p)/m .... divide both sides by m
a = (n+p)/m ... notice how the 'm's cancel out when we divide on the left side
Final Answer: a = (n+p)/mYou must use parenthesis to indicate that all of "n+p" is over m or you can write it like this
