The value of x when Ray AE intersects ray AB at a right angle with ray A.F is A. 10°.
How to calculate the angle?
It should be noted that based on the information given,they intersected a the right angle. It should be noted that a right angle has a value of 90°.
Therefore, 4x + 5x = 90°
Collect like terms
9x = 90°
Divide
x = 90° / 9
x = 10°
Therefore, the value of x is 10°.
