Remark
You can get an idea of how this should be solved by drawing a diameter from the intersection of the tangent and the circumference of the circle and the center of the circle. When you do this and when you draw an angle from either side of the diarmeter joining the two ends of the diameter to the circumference of the circle you get 90 degrees. See the first diagram on the left.
Now what you want is the chord tangent theorem.
The angle at the intersection of the chord and the the tangent point is one half the size of the arc formed by the endpoints of the chord and the circumference of the circle. See diagram on the right.
step one
Draw a line showing what you are talking about.
Step two
82 * 2 = 164

Answer:
The unknown sides are 60.81cm and 51.57cm while the unknown angle is 58degrees
Step-by-step explanation:
4a) Given the following
Opposite side = 38cm (side facing the given angle)
Required
Adjacent and hypotenuse side
According to SOH CAH TOA
Next is to get the adjacent
Next is to get the missing
Since sum of angle in the triangle is 180degrees
32 + 90 + x = 180
122 + x = 180
x = 180 - 122
x = 58degrees
Answer:
where x₁ and x₂ are values in the interval [x,y] respectively
Step-by-step explanation:
Well, first to determine the average rate of change of a function, you should have the interval of the values of x for the function.
So lets assume you have a function;
And the interval as [1,3]
Then the average rate of change for the function f(x) will be;
where x₁ and x₂ are the interval coordinates x,y respectively. In this case x₁=1 and x₂=3
To find the average rate of change in this example will be;
