Solve polygon angle sum

x = 95

Step-by-step explanation:

You already know the sum of angles in a polygon is (n-2)180° where n is the number of sides so we can find out the sum of angles in this polygon and then find x.

Sum of angles in polygon = (5-2)180°

                                           = 3×180°

                                           = 540°

x + 104 + 117 + 100 + 124 = 540

x = 540 - 104 - 117 - 100 - 124

x = 95

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

the area of ​​the surface of the rectangular prism here is 250 cm2, which is the surface of the shading
