Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°
X = 5x + 6
Bring the x terms to the same side
x - x = 5x + 6 - x
0 = 4x + 6
Move the 6 to the opposite side
0 -6 = 4x + 6 - 6
-6 = 4x
Divide by 4
x = - 3/2
