Complementary angles are those angles whose sum is 90 degree.
The measurement of two complementary angles are
![(2x-10), (3x-10)](https://img.qammunity.org/2019/formulas/mathematics/high-school/r9xl3b5vcgrdoda8gz50wqp4nmef65wfo5.png)
There sum have to be 90 degree. That is
![2x-10+3x-10 = 90](https://img.qammunity.org/2019/formulas/mathematics/high-school/tb4t5upofjubh7uv9e2zxrer6g65kjjfjn.png)
Combining like terms ,
![5x - 20 = 90](https://img.qammunity.org/2019/formulas/mathematics/high-school/ofpzrt4hjrfpjqjvgyl7zdosfdmzm33t0g.png)
Moving 20 to right side
![5x=110](https://img.qammunity.org/2019/formulas/mathematics/high-school/nx80eg7ne5mw09eqeqp6hqxf3icc79d85b.png)
Dividing both sides by 5
![x =22](https://img.qammunity.org/2019/formulas/mathematics/high-school/jc6bojk0g35a4herph8c4drght7ji5lqz6.png)
So the measurement of the angles are
![2*22-10 , 3*22-10 \\ 34 degree, 56 degree](https://img.qammunity.org/2019/formulas/mathematics/high-school/bpjl1co9kzud6luol0wvii2f4k9q3ojnyy.png)
