Answer:
X = 20, A = 125
Step-by-step explanation:
A and B are alternate angles and all alternate angles are equal,so therefore A and B are equal
A =B
A = 6x + 5 and B =4x + 45
Therefore 6x +5 = 4x + 45
Collect like terms
6x - 4x =45 - 5
2x =40
X = 40/2
X = 20
Substitute X in the first equation
A = 6x + 5
A = 6(20) + 5
A = 120 + 5
A = 125
I hope this helped
