Answer:
x° = 77.7°
Step-by-step explanation:
We know that the interior angles within a quadrilateral add up to 360 degrees. We are provided with two right angles and a third angle of 102.3°. So we must solve to find x.
90 + 90 = 180
102.3 + 180 = 282.3
360 - 282.3 = 77.7
x = 77.7 degrees
The answer to this is y=13
5 x 5 x 5 = 125
since the perimeter is 20, and there are four sides, each side would be 5 since it is a square. then you do l x w x h and get 125
2x + 5 > 9 and 5x ≤ 30
- 5 - 5 5 5
2x > 4 x ≤ 9
2 2
x > 2
Solution Set: {2 < x ≤ 9}, (2, 9]
