Answer:
10
Step-by-step explanation:
LN = 4 + x - 8 = x - 4
LS = 3 + x - 5 = x - 2
By intersecting secants theorem:

Area is length x width
Area = 2/5 x 3/4
When multiplying fraction, multiply the numerators by each other and the denominators by each other:
Area = 2/5 x 3/4 = (2 x3)/(5 x 4) = 6/20
6/20 reduces to 3/10
Area = 3/10 square yards
88 degrees would be the correct amount
