Answer:
a = 44 degrees
Step-by-step explanation:
- Triangle AOB is an isosceles triangle.
- Angle A and B are same.
- All three angles of a triangle are equal to 180 degrees.
angle 0 + angle a + angle b = 180 degrees
angle b = angle a
92 + a + b = 180 degrees
92 + 2a = 180 degrees
a = 44 degrees

Answer:
Step-by-step explanation:
we know that
The area of a trapezoid is equal to
where
b1 and b2 are the parallel bases
h is the height of trapezoid (perpendicular distance between the two parallel bases)
In this problem the area is equal to
we have the coordinates
the formula to calculate the distance between two points is equal to
step 1
Find the distance AB
substitute in the formula
step 2
Find the distance BC
substitute in the formula
step 3
Find the distance AD
substitute in the formula
step 4
Find the area
substitute the values
