This is true. you don't need to provide a counterexample
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
Answer:
The measure of each angle will be 10° and 170°.
Step-by-step explanation:
A supplementary angle refers to an angle that has the sum to be equal to 180°.
Let the small angle be represented by x
Therefore, the big angle will be: = 17 × x = 17x
Therefore, the value of both angles will be:
x + 17x = 180
18x = 180
Divide both side by 18
18x/18 = 180/18
x = 10
Therefore, the bigger angle will be:
17x = 17 × 10 = 170
Therefore, the angles are 10° and 170°
T. In bag one there is 1/9 probability that you will get a 2 and in bag 2 there is a 1/5 chance that you will get a U then you multiply them and you get 1/45 chance
Find the fraction of so E there is a 4/9 chance that you will get an even number 2, 4, 6, and 8 and a 1/5 chance that you will get a I you multiply and you get 4/45 chance
(y2-y1)÷(x2-x1) so 11.5-2.5 divided by -2.6+5.6 and the answer is 3
