Answer:
Step-by-step explanation:
we know that
In an inscribed quadrilateral ABCD opposite angles are supplementary
so
----> equation 1
----> equation 2
step 1
Find the value of x
substitute the given values in equation 1
step 2
Find the measure of angle A,C and D
substitute the value of x
step 3
Find the measure of angle B
Remember the equation 2
----> equation 2
substitute the value of D
I think that the answer would be 100. If I'm wrong, whoops! I'm not perfect, in fact nobody is.
