Answer:
m<0 = 50
Step-by-step explanation:
The opposite angles in an isosceles trapezoid are equal, so <T = <A
and <B = <O
We know the sum of all 4 angles has to be 360 since it is a quadrilateral
<T+<A + < B + <O = 360
Substituting what we know, and what we want to know
<T+ <T + <O <+O = 360
Combining like terms
2<T + 2 <0 = 360
2( 130) + 2<0 = 360
260 + 2< O = 360
Subtract 260 from each side
260-260 + 2< O = 360-260
2<O = 100
Divide by 2
2/2<O = 100/2
<0 = 50
