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
