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

Step-by-step explanation:
I think since am still in secondary school
it's should be (x-4)(x-4)
(6,-6) seeing that in the original the x is 3 when you go righ
