Answer:

143

Step-by-step explanation:

Substitute n=3 into the problem

6( $3^{3}$ )-2( $3^{2}$ ) +3-4

Then figure out squared and power by 3

6(27)-2(9)+3-4

Next multiply

162-18+3-4

Finally, add and subtract

144+3=147

147-4=143

How do you find the missing angle of a triangle when all other angles are there?

olya-2409 [2.1K]

All angles in a triangle add up to 180 degrees. So, if you are missing an angle, add up the degrees of the angles present and subtract that from 180. That will be the value of the missing angle in degrees.
