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.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
