Answer: <em>x = 59°, y = 114°.</em>
Step-by-step explanation:
<em>The sum of the opposite angles of a quadrilateral in a circle is 180°.</em>
<em>y = 180° - 121° = 59°</em>
<em>The two angles being adjacent makes a total angle of 180° on the straight line.</em>
<em>x = 180° - (180°-114°) = 180° - 66° = 114°</em>
Next time, please be specific about your goal: "Solve for x; write your answer as a fraction."
The first step here is to combine the x-terms within the parentheses:
9(-5x) = 0
The second step is to perform the indicated multiplication:
-45x = 0
Dividing both sides by -45, we get x = 0. Ensure that you have copied down this problem correctly.

To solve this problem we need to know the equivalence between yards and inches, that is:
1 yd = 36 inches
Therefore in 8 yd we have:
8(36) = 288
so in 8 yd we have 288 inches
So 8 yd is equal to 288 in
Answer:
Step-by-step explanation:
x²+10x+21=0
x²+10x+(10/2)²-(10/2)²+21=0
x²+10x+25-25+21=0
(x+5)²-4=0
(x+5)²=4
(x+y)²=(x+y)(x+y)=x(x+y)+y(x+y)=x²+xy+xy+y²=x²+2xy+y²
(x+y)²=x²+2xy+y²
coefficient of x=2y
y²=[(coefficient of x)/2]²=(2y/2)²=y²
