Answer:
56
Step-by-step explanation:
Assuming that the corner of the fence has right angle, the the area that the dog wandered will be given by:
A=θ/360πr²
Where:
θ=360-90=270°
r=49 ft
hence the area will be:
A=270/360×π×49²
A=5657.23 ft²
Thus the dog will wander in the area of 5657.23 ft²

Answer:
70
Step-by-step explanation:
another angle is 150 - 130 degree
so look at the triangle
we know x + 90 + 20 = 180 degree
so x = 70 degree
