Answer:
Step-by-step explanation:
Perimeter of rectangle given = 26 cm
And measure of a side of the rectangle = 5 cm
Since perimeter of a rectangle = 2(length + width)
By replacing the values of perimeter and length in the formula
26 = 2(5 + width)
5 + width =
width = 13 - 5 = 8 cm
Now we can draw a rectangle of length = 5 cm and width = 8 cm

The value is from -6 not including -6 to infinity
-6 < y < ∞
Answer:
C. from -6 to infinity
Step-by-step explanation:
The range is the set of the y-coordinates of the points of the function.
The lowest value of y is -6 or just greater than -6.
All values greater than y are also part of the range.

Answer:
Step-by-step explanation:
In a right-angled triangle, the tangent ratio of an acute angle = the ratio of the length of the opposite side to the length of the adjacent side.
Lets say angle A= 150 degrees (obtuse)
- to find its corresponding acute angle, we need to subtract 150 from 180 degrees, that is, 180-150= 30 degrees.
- Considering a right triangle where angle B=30 degrees. now assuming that the opposite side of angle B has a length of 7 while the adjacent side has a length of 25.
So, the tangent ratio of angle B= the ratio of the length of the opposite side to the length of the adjacent side.
So far we have:
- tan B = opposite/adjacent = 7/25
and because angle A is obtuse, its tangent ratio is the negative of the tangent ratio of its corresponding acute angle.
- So, tan A = -tan 30 = -1/√3 or approximately -0.577.
Step-by-step explanation:
first of all
tan(x) = sin(x)/cos(x)
that is the tangent ratio.
so, the question is also, what happens to sine and cosine for obtuse angles.
remember the trigonometric triangle inside the circle.
sine is the up/down leg (up = positive, down = negative), cosine is the left/right leg (and extension of the leg; of left from the center = negative, if right from the center = positive).
so, for an obtuse angle (90° < angle <= 180°) sine is still up and therefore positive, but cosine is left from the center and therefore negative.
for that reason tan(angle) = sin(angle)/cos(angle) is negative.
in fact, it is -tan(180 - angle).
