<u>Answer </u><u>:</u>
In the given quadrilateral ABCD ,
Angle BCA = 18° Angle ACD = 62°
Angle BCA = Angle CAD ( alternate interior angle )
Now in triangle CAD ,
We have two angles so by using angle sum property we can find the required third one ,
Angle CAD + Angle ACD + Angle ADC = 180° 18 + 62 + Angle ADC = 180 80 + Angle ADC = 180 Angle ADC = 180 - 80 Angle ADC = 100
Answer:
∠ ADC = 100°
Step-by-step explanation:
∠ CAD = ∠ BCA = 18° ( alternate angles )
The sum of the 3 angles in a triangle = 180° , then
∠ ADC = 180° - (62 + 18)° = 180° - 80° = 100°

If you use a table you see all the fractions next to each other and you see what did I do the get from this fraction to this fraction.
