Plsss help me .I’ll send you as many points as you want just please answer the question in the picture .It so easy for most of you guys .

Scalene just means all the angles are different.  Not particularly helpful; we'll check at the end.

Obtuse is bigger than 90, so this will be the biggest angle in the triangle, let's call it A.  A>90 degrees.

B=56 degrees.  

C is the smallest angle.  It will be smaller than B, since A is obtuse.

The two equations we can write are

A = 3C

A+B+C=180

3C + 56 + C = 180

4C = 124

C = 31

A = 3(31) = 93

Check:

31 + 93 + 56 = 180, good

all three different, scalene, good

93 is obtuse, good

Triangle has angles 31°, 56°, 93°

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
