Can someone please help me with this question??

540

Step-by-step explanation:

Formula for calculating the sum of interior angles is ( n − 2 ) × 180

Where n = number of sides

The polygon shown has 5 sides so n = 5

To find the sum of the interior angles we simply plug in the values of n into the formula

( n − 2 ) × 180

plug in n = 5

( 5 - 2 ) × 180

Subtract 5 and 2

3 × 180

Multiply

= 540

And we are done

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
