- b. what is the value of x in the figure?
triangle with ( x^circ ), ( 49^circ ), and exterior angle ( 104^circ )
enter your answer.
Step1: Recall triangle exterior angle theorem
The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. So, if we let the exterior angle be \(104^{\circ}\), one non - adjacent interior angle be \(x^{\circ}\) and the other be \(49^{\circ}\), we have the equation \(104=x + 49\).
Step2: Solve for x
To find \(x\), we subtract \(49\) from both sides of the equation.
\(x=104 - 49\)
\(x = 55\)
