To find the difference of this problem, start by simplifying the denominator, which will look like . Next, multiply by to create a fraction with a common denominator in order to subtract from . The problem will now look like .
Then, simplify the terms in the problem by first multiplying and , which will look like . The next step is to combine the numerators over the common denominator, which will look like .
Next, simplify the numerator, and to simplify the numerator start by factoring 3 out of , which will look like . Then, subtract 14 from -7, which will look like . The final answer will be .
Answer:
Look below.
Step-by-step explanation:
One property of a cyclic quadrilateral is that the opposite angles are supplementary. Angles ABC and ADC are opposite; therefore, supplementary. We know that angle x is supplementary to angle ABC because they are on the same line. We know that angle y is supplementary to angle ADC because they are on the same line.
ABC + ADC= 180 degrees
ABC + x= 180 degrees
ABC + ADC = ABC + x
- ABC -ABC
ADC= x
ADC+ y= 180 degrees
ADC + ABC= 180 degrees
ADC+y= ADC+ABC
-ADC -ADC
y=ABC
ABC=x ADC=y
ABC + ADC= 180
Property of substitution:
x+y=180
