Explanation:
The sum of the interior angles can be found with (n-2)
![180^o](https://img.qammunity.org/2022/formulas/mathematics/college/s30tffe5jppeah9jwjmc68q9t7zvg8mens.png)
Where n is the number of sides
(6-2)
![180^0](https://img.qammunity.org/2022/formulas/chemistry/college/cllvbcqxjibe8naiopfu0why2s8vdwk314.png)
This shape has a total interior angle measurement of
![720^0](https://img.qammunity.org/2022/formulas/mathematics/high-school/xla0u6dlmrr74h8ityu9x0w1vpl71avqnq.png)
Since there are two given right angles we can subtract those
![720^o-180^0=540^o](https://img.qammunity.org/2022/formulas/mathematics/high-school/14f403oqgwc1prtq2w0i51njeqp7jv5rbo.png)
We have four spots for x so:
x=
![(540^o)/(4)](https://img.qammunity.org/2022/formulas/mathematics/high-school/rc6x5wc8tx689yox6lzjf2ysx7902u8iun.png)
x=
![135^o](https://img.qammunity.org/2022/formulas/mathematics/high-school/lkbpfik3y4t9adxr99lie3ka9h52gphzau.png)
