Answer:
Step-by-step explanation:
cos^-1(6/13)=62.5136°
sin(2*62.5136°)=0.8189
cos(2*62.5136°)=-0.5740
Yes the triangles are congruent by the HL Theorem

Answer:
Jamison is not correct
Step-by-step explanation:
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
These roots comprises of real roots and imaginary roots.
The given function is

Based on the Fundamental Theorem of Algebra, this function should have four roots.
The graph of the function only reveals real zeros and not the imaginary zeros.
So aside −4 and 5, there are two complex zeros
Answer:
I would guess the 30 degree one.
