Which set of angles can be used to construct a triangle?

A) 72°, 73°, and 54°
B) 88°, 34°, and 58°
C) 89°, 46°, and 54°
D) 95°, 50°, and 27°

The answer is b.

Step-by-step explanation:

This is because the sum of the three angles of a triangle are always 180 degrees so when you all the possibilities up to check you find out the only b adds up to 180.

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..
