Find the value of x.
72°
108°
x°
72°
72 + 72 + 108 + x = 360
252 + x = 360
X = 108°
Find the value of x.
102°
x°
2x°
90°
102 + 90 + 2x + x = 360
192+ 3x = 360
3x = 168
X= 56°

A = 21 cm2
Find the area of the polygon.
A= bh
A = (7) (8)
A = 56 cm2
Find the area of the polygon.
A= ½ h (a + b)
A = ½ (10) (7 + 15)
A = 110 cm2
