4,7
Step-by-step explanation:
17x+6=19x-2(being vertically opposite)
6+2=19x-17x
8=2x
x=8/2
x=4
10x-5=9+8x(being corresponding angle)
10x-8x=9+5
2x=14
x=14/2
x=7

Answer:
(3/4)pi
Step-by-step explanation:
Find the areas of the two circles and then subtract the smaller from the larger:
A of circle = (pi)r^2
Case 1: r = 1 unit: A = (pi)(1) = pi
Case 2: r = 1/2 unit: A = (pi)(1/2)^2 = pi/4
The area lying outside of the smaller circle is therefore (pi) - (pi)(1/4) = (3/4)pi
