Answer:
Answer is the third one/ or c
Step-by-step explanation:
Answer:
While determining the angle 
with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.
Step-by-step explanation:
See the diagram attached.
Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB = and the sides AB, BC, CA are 3, 4, 5 units respectively.
The tangent ratio of an angle is given by
Again, the cotangent ratio of angle is given by
Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)
Answer:
28 units
Step-by-step explanation:
Since the perimeter of both triangles is same,
the sum of all sides of first triangle = sum of all sides of second triangle
or, 6x + 3 + 2x + 4x = 5x + 5x + 3x + 2
or, 12x + 4 = 13x + 2
or, 4-2 = 13x - 12x
or, 2 = x
Now,
Putting the value of x in the perimeter of first triangle,
12x + 4= 12* 2+ 4
= 28 units
Answer is D. No negative in front because the parabola opens upwards. x+3 moves it left 3. And - 1 moves it down one
AB = 13 because AB = TU and TU = 13
