4(2+3-1)=16
3(2+4)-1=17
3*1(2+4)=18
4(2+3)-1=19
4*1(2+3)=20
The Area of the shaded region = (Area of the largest circle) – (Area of the circle with radius 3) – (Area of the circle with radius 2). Whatever is left over is the shaded region. The diameter of the largest circle is 10, so its radius is 5 and thus its area is 25π
Answer:
Step-by-step explanation:
[logical equivalence]
[morgan laws]
if is true, then is true and is too.
with true, then is false [double denial]
In the first equivalence it follows that is true [identity law]
Then it can be concluded that
They are corresponding angles - they are equal
X+95 =4x-10
Add 10 to both sides
X+105 =4x
Subtract x from both sides
105=3x
X=35
35+95= 130
