-16 because you need to subtract -4 from -12
M < 2 and m < 6 are corresponding angles and are equal....so < 6 = 132.
< 6 and < 8 form a line and are equal to 180
< 6 + < 8 = 180
132 + < 8 = 180
< 8 = 180 - 132
< 8 = 48 <===
Answer:
No
Step-by-step explanation:
By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.
Thus,
where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then




which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.
Answer:
$20 per sweater.
Step-by-step explanation:
It is given that,
A store buys 7 sweaters for $42 and sells them for $182.
We need to find how much profit the store make per sweater.
The amount the store bought the sweaters fr is calculated as follows :
$182- $42 = $140
Profit the store made per sweater is given by :

Hence, the store will make $20 per sweater.
