20% of 25 is 5 hope this helps
Area of sector = PI x r^2 x (angle/360)
area = PI x 10^2 * (45/360)
area = PI x 100 * 45/360
Area = 25/2x PI
Area = 25PI/2
Answer is D
Let's say that the number we are looking for is called 'x'.
3 * x = 40
3x = 40
To solve for 'x', we will need to divide both sides by 3.
3x/3 = 40/3
40/3 or 13 1/3 can be multiplied by 3 to get 40.
Answer:
X= 78
Step-by-step explanation:
180-115=65 that's one of the angles
and the other one is 360-323=37
and add the two angles together = 102
then finally 180-102=78 and that's it
