In the given figure. BEST is a rectangle in which diagonals BS and
TE intersect at O EOS=50, then find ZOBT
(A) 56
(B) 45
(C) 65
(D None of these

Answer 1

Answer: none of these

Step-by-step explanation: angle bot =50 as vertically opposite angles

Angle otb =45 as et bisects angle t which is 90 degree

50 +45+angle obt=180 angle sum property

95+obt=180

Obt =180-95

Obt =85
