Answer:

x=15º

Step-by-step explanation:

Sum of quadrilateral interior angles;

(4x + 25) + (3x + 25) + (6x + 20) + 180-(4x + 25)=360

3x + 25 + 6x + 20 + 180 =360

9x = 360 - 225

9x = 135

x = 15º

Answer:

x = 15

Step-by-step explanation:

the opposite angle of a cyclic quadrilateral sum to 180° , then

6x + 20 + 3x + 25 = 180

9x + 45 = 180 ( subtract 45 from both sides )

9x = 135 ( divide both sides by 9 )

x = 15

The ordered pair (a,b) satisfies the inequality y>x+10. Which statement is true?

Morgarella [4.7K]

Answer:

$b-a>10\\\\Difference\ of\ b\ and\ a\ is\ greater\ than\ 10.$

Step-by-step explanation:

Ordered Pair: In an ordered pair (p,q) first value that is p represents x-value and second value(q) represents y-value.

$Given\ inequality\ y>x+10\\\\Ordered\ pair (a,b)\ satisfies\ the\ inequality\\\\Hence\ x=a,\ y=b\\\\Substitute\ these\ values\ in\ the\ inequality.\\\\b>a+10\\\\\Rightarrow b-a>10\\\\That\ means\ difference\ of\ b\ and\ a\ is\ greater\ than\ 10.$
