Answer 1

Answer:

X=154

Step-by-step explanation:

Draw a perpendicular joining a and c

Now angle OAC=10

And angleOCA=16

Since total sum of triangle are 180

Angle AOC=180-(26)=154

Answer 2

Step-by-step explanation:

AB||CD

Now join AC

then angle BAC = 90

also angle CDA = 90

then angle OAC = 100 - 90

then angle OAC = 10

similarly

then angle OCA = 106 - 90

so angle OCA= 16

Now in triangle OAC

angle O + angle OCA + angle OAC = 180

by putting value

angle O + 16 + 10 = 180

angle O = 180 - 26

angle O = 154

therefore X = 154
