All of those are congruency short-cuts. S stands for side, A stands for Angle. Using these shortcuts, we can prove congruency in triangles easier. in the problem above, we are given a pair of angles that are congruent and a side that is congruent. Using the vertical angle theorem, we have two angles and 1 side so both those triangles would be congruent by AAS.
There are two congruency methods that don't work. There's SSA and AAA, For number 3, it would be congruent by ASA, not AAS, and for number 4, it would be congruent by AAS, or SAA, SAA is more used.
Area is length * width. Since the area is 44 and the length is 5.5, to find the width, simply divide the area by the length.
44 square feet / 5.5 feet = 8ft width
Answer:
y=66 z=180-74=106 x=60
Step-by-step explanation:
Answer:
The correct option is;
Step-by-step explanation:
The given parameters are
The equation of motion of one (the first) object is r = 4·cos(θ)
The equation of motion of the other (the second) object is r = -1 + 2·cos(θ)
Equating both equations gives;
4·cos(θ) = -1 + 2·cos(θ)
4·cos(θ) - 2·cos(θ) = -1
2·cos(θ) = -1
cos(θ) = -1/2
θ = Arccos(-1/2) = 120° = 2·π/3
Therefore, the two equations are equal when θ = 2·π/3 for which we have;
r = 4·cos(2π/3) = -2 and r = -1 + 2·cos(2π/3) = -2
∴ r = 4·cos(2π/3) = -1 + 2·cos(2π/3) = -2
The coordinate that represents a possible collision point of the objects in the form (r, θ) is therefore
4
