Answer:

Step-by-step explanation:
Step 1
Find the value of x
we know that
In an inscribed quadrilateral the opposites angles are supplementary
so
In this problem

substitute the values and solve for x




step 2
Find the measure of angle B

substitute the value of x

The two numbers are 12 and 16. 12 + 6 = 18. 6 doubled is 12. 12 plus 6 equals 18.
7,14,21,28,35
Multiply 7 by 1-5
{(3x)}^{2}-2(3x)(5)+{5}^{2}
−2(3x)(5)+5
2
{(3x-5)}^{2}
-1/3
An example that goes through step by step is below:
The Multiplicative Inverse Property. What number can we multiply to 8 to get 1 (the multiplicative identity) as the answer? So, the multiplicative inverse of 8 is 1/8!
