Answer:
the minimum value of the given function is -4
Y(3y-4)
The y can be factored out of both equations
1) Tanθ= opposite/adjacent
θ=Tan-1(9/7)
θ=52.125 = 52 degrees
2) Cosθ= adjacent/hypothesis
θ=Cos-1(5/12)
θ=65.376 = 65 degrees
The answer is 9 because its an odd number, not the sides of a triangle, can be divided be 3, and is a single digit number.
The two sides marked 7 are congruent.
Sides AC and AD are congruent.
Sides BC and ED are congruent.
By SSS, the triangles are congruent.
Also, angles BAC and EAD are congruent, so by SAS, the triangles are congruent.
Answer: A. yes, by either SSS or SAS
