Find the area of the trapezoid.

A = 179.4 km^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+b2) h where b1 and b2 are the lengths of the bases and h is the height

A =1/2 ( 7.6+20) * 13

A = 1/2 (27.6) 13

A = 179.4 km^2

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
