Answer:
x° = 80°
Step-by-step explanation:
[tex] {x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ [/tex]
(The measure of the interior angle of a square is 90°)
[tex]{x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ {x}^{o} + {280}^{o} = {360}^{o} \\ {x}^{o} = {360}^{o} - {280}^{o} \\ {x}^{o} = {80}^{o} \\ [/tex]
