Can someone help me here

Answer 1

Answer:

Step-by-step explanation:

Remark

When a quadrilateral is inscribed in a circle, the opposite angles are supplementary. x is opposite 112 degrees. Therefore x and 112 add up to 180 degrees.

Formula

x + 112 = 180                      Subtract 112 from both sides.

Solution

x + 112-112 = 180 - 112

x = 68

Answer

x = 68

Answer 2

Answer:

Step-by-step explanation:

#9.

x° = 200° and x = 200

y° = 100° and y = 100

#10.

x° = 68° , x = 68

y° = 99° , y = 99
