∠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°
Answer:
Step-by-step explanation:
Draw a picture. You have an isosceles right triangle. Each leg is 50 ft.
tanθ = 50/50 = 1
θ = arctan(1) = 45°
your answer will be the last one
