Quadrilateral abcd is inscribed in this circle.

what is the measure of angle a?

The measure of angle A =  65°

Step-by-step explanation:

The sum of opposite angles of cyclic quadrilateral is 180°

From the figure we can see that,quadrilateral ABCD is inscribed in a circle.

To find the value of x

m<B + m<D = 180°

x + 148 = 180

x = 180 - 148 = 32°  

To find the value of angle A

m<A = 2x + 1

x = 32

m<A  = 2*32 + 1 = 64 + 1 = 65°

Therefore the measure of angle A =  65°

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
