Answer:-
x=110 degree
Step-by-step explanation:
It's quadrilateral so it's total sum degree is 360
then 40+82+128+x=360
360-(128+82+40)=X
x=360-250
x=110 degree
I think it would be abdce?
The tangent AD at point C forms a right angle to circle B, such as ∠ACB=90° and ∠ABC=55°.
We also know that the summation of all angles in a triangle is 180°. Thus we have the expression below:
180°=∠ABC + ∠ACB + ∠BAD
180°=55°+90°+∠BAD
∠BAD=35°
Therefore, the answer is 35°.

Answer:
80
Step-by-step explanation:
720/P = 9/1
Cross multiply.
9P = 720
P = 720/9
P = 80
