Answer:
55
Step-by-step explanation:
took the test
X=12. So this one says that it has 3 congruent sides so therefore it has to have 3 congruent angles. Here we have angle 2 and we have angle 60. Given the definition of triangle congruence, we can say that 60 is angle 2 and that the third angle is also 60 but it’s not relevant in this problem. So knowing that angle 2 is 4x+12 we solve for x by seeding that equal to 60 and then solving for x we get x=12. Hope this helps!!!!

Step-by-step explanation:
Answer: x = 84°.
Step-by-step explanation: The sum of interior angles of a quadrilateral is equal to 360°. We are given three of the interior angles and asked to find the remaining angle. To do this, we can add the three given angles and subtract the sum from 360°. 53° + 125° + 98° = 276°. 360° - 276° = 84°. Thus, x = 84°.
