Explanation:
Hey there!!!
Here, ABCD is a parallelogram.
We know that the one property of a parallelogram is:
- It's opposite angle are congruent or equal.
So,
3x-10° = x+45°
or, 3x - x = 45°+10°
2x = 55°
![x = (55)/(2)](https://img.qammunity.org/2021/formulas/mathematics/college/ayc32m91guj0ehca4t1ob9uhnfeixetm0h.png)
Therefore the measure of angle x is 27.5°.
Hope it helps....
