Step-by-step explanation:
It's False.Sine is a trigonometric function of the angle in a right triangle is equal to the ratio of the opposite leg to the angle of the hypotenuse.
∠AXY=∠XBC=55°(corresponding angles)
XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°
The sum of all the angles in a triangle is 180°⇒
55°+55°+∠BXC=180°
∠BXC=70°
