Question

Find the value of x.
115
x
95
70

Answer 1

x° = 80°

Explanation:

`{x}^(o) + {115}^(o) + {95}^(o) + {70}^(o) = {360}^(o) \\`

(The measure of the interior angle of a square is 90°)

`{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) \\`
