Classify the following triangle. check all that apply.

a. scalene
b. right
c. equilateral
d. isosceles
e. obtuse
f. acute

Step-by-step explanation:

a. scalene  :  Reason: all angles and sides are different measurements.

f. acute : all the three angles are acute (Less than 90)

A. Scalene

F. Acute

Step-by-step explanation: Although this may look like an equiladeral triangle, it is actually scalene. If it were an equiladeral triangle, it would have sides that are all the same length and angles. The triangle shown has all three different side lengths, hence, it is scalene.

The angles are also alal acute, meaning the are less than 90 degrees.

Let me know if you have any other questions regarding this topic. :)

idk

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
