Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.
Answer:
4/10
Step-by-step explanation:
1/2 - 1/10
We need to get a common denominator of 10
1/2 * 5/5 = 5/10
Replace 1/2 with 5/10
5/10 - 1/10
4/10
This simplifies by dividing the top and bottom by 2
4/2 =2
10/2 = 5
2/5
Answer:
80 degrees because if you look at 1 its 62 plus 18
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
