Answer:
(x+11)(x-11) its a difference of squares formula, when you FOIL it out the positive 11x and negative 11x will cancel out
Step-by-step explanation:
M∠ADB + m∠BDC = m∠ADC [<span>angle addition postulate]
x + x + 10 = 60
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25
a
m</span>∠ADB = x = 25°
b
m∠BDC = x + 10 = 25 + 10 = 35°
It will reflect the same distance over the Y axis, from the right side of the graph to the left side of the graph.
