Answer:
25
Step-by-step explanation:
sin © =36/(35+x)=21/35
36/(35+x)=21/35
x=(36*35/21)-35
x=25
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2

Answer:
2³·3²·x·y²
Step-by-step explanation:
Unique prime factors are 2, 3, x, y. Each of those is raised to a power to obtain the given expression.
72xy² = 8·9·x·y² = 2³·3²·x·y²
