Answer:
Consider a right angle triangle ABC such that B =90 degree as shown in figure given below with all the three sides labelled.
let
Sum of all the measures of an angle in a triangle is 180 degree.
In triangle ABC
or
Simplify:
The side AC (Hypotenuse) = 10 cm
Now, find the other sides i.e, AB and BC;
Using Sine rule
In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse side.
then
or
or
Simplify:
AB = 6.4278761 ≈ 6.43 cm
Now,by using tangent rule to solve for BC
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
then;
or
or
Simplify:
BC = 7.66044443≈ 7.66 cm
therefore, the sides AB and BC of the triangle ABC are 6.43(approx) and 7.66(approx.)
Answer:
Domain: [2,∞)
Range: [0,∞)
Step-by-step explanation:
Domain are the values of <em>x</em> allowed for the function.
In this function, because we have a square root, we cannot have numbers in the domain such that the root contains a negative number, because the function would not be defined in real numbers.
Thus, the domain is:
Domain= x-2 ≥ 0
Domain = x ≥ 2
Or what is the same [2,∞)
And the range is the values that the function returns for every number in the domain. Since our domain is the values of x greater than or equal to two:
We can see that the minimum value of y = f (x) is 0 and the greatest number that the function can return to us has no limit, so the range is:
Range: [0,∞)
Answer:
No graph attached, but it would look like;
The y intercept (the line which meets the y axis) would be at positive 2,
it would then rise one and go over 3 to the right because they are both positive.
