Answer 1

x = 2.93

Explanation:

The sum of angles of the triangle is 180degrees, hence;

9x - 72 + 73x + 11 = 180

82x - 61 = 180

82x = 180 + 61

82x = 241

Divide both sides by 82

82x/82 = 241/82

x = 2.93

Note that the functions might not be accurate but the same methos should be employed for any function given
