Classify the following triangle. check all that apply.
answer must be correct. im taking a quiz and i really need to pass it.
a. equilateral
b. right
c. obtuse
d. acute
e. scalene
f. isosceles

The correct option is D - acute triangle.

Step-by-step explanation:

A.equilateral  - An equilateral triangle has all the sides and angles equal, so this is not the answer.

B.right  - A right triangle has a 90 degree angle in it. So this is also not correct.

C.obtuse  - Obtuse triangles are those which have angle greater than 90 degrees, so this is also not correct.

D.acute  - Acute triangles have all angles less than 90 degrees. So, this is the answer.

E.scalene  - A scalene triangle has all three sides unequal but angles can be obtuse or acute. So this is not the answer.

F.isosceles - An isosceles triangle has 2 sides equal. So, this is also not correct.

Therefore, the correct option is D - acute triangle.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
