Sagot :
Answer:
1. each angle measures 80° and 100°
2. 22 cm
Step-by-step explanation:
1. opposite angles of isosceles trapezoid are supplementary, so it would be x+x+20=180
2x=160
x=80, so it means that each angle measures 80° and 100° respectively.
2. the area of kite is half the product of its diagonals, so
[tex]A=\frac{1}{2} d_{1} d_{2} \\176=\frac{d_{1}(16) }{2} \\\\352=16d\\d=22cm[/tex]
