Answer:
Step-by-step explanation:
In the given picture, a parallelogram PQRS is given with angle 101°.
In a parallelogram opposite angles are equal.
Since, y is opposite to 101°.
Therefore y=101°
Also, the sum of the adjacent angles of a parallelogram is 180°
Answer:
15
Step-by-step explanation:
By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is . Simplifying the equation
, gives
. Substituting
in the equation for segment AC gives 15.
