Because all angles of a triangle add up to 180 and we already know two of the angle values you would subtract them from 180 to get your answer
180-45-55=80

your answer is 80 degrees

HELP!!THANKS FOR ACCURACY
anyanavicka [17]

\bf tan^2(x)-1=0\implies tan^2(x)=1\implies tan(x)=\pm\sqrt{1} \\\\\\ tan^{-1}[tan(x)]=tan^{-1}(\pm 1)\implies x=tan^{-1}(\pm 1)\implies x= \begin{cases} \frac{\pi }{4}\\\\ \frac{3\pi }{4}\\\\ \frac{5\pi }{4}\\\\ \frac{7\pi }{4} \end{cases}

Angle ABD and angle BDE are supplementary. Find the measures of both angles.
marishachu [46]
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9

∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°
