Question

Find the value or measure. Assume all lines that appear to be tangent are tangent.mBEA=

Answer 1

step 1

Find out the measure of arc AB

angle so

msubstitute the given value

74=(1/2)arc AB

arc AB=148 degrees

step 2

we have that

arc AB+arc BEA=360 degrees ------> by complete circle

so

148+arc BEA=360

arc BEA=360-148

arc BEA=212 degrees
