Solve for × and then find the missing angle in
the triangle below. SHOW ALL WORK.

Answer:
x = 4°
Step-by-step explanation:
all angles in a triangle sum up to 180°
6x + 38° + 5x + 8° + 90° = 180 °
11x +136° = 180°
11x = 44°
x = 4°
Answer:
The value of x is 4.
Step-by-step explanation:
As we know that the sum of interior angles of triangle is 180⁰.
So, adding all the given sides and subtracting to 180⁰, to find the value of x.
[tex]\begin{gathered} \quad{\implies{\sf{Sum\:of\:all\: angles={180}^{\circ}}}}\\\\\quad{\implies{\tt{6x + {38}^{\circ} + {90}^{\circ} +5x + {8}^{\circ} = {180}^{\circ}}}}\\\\\quad{\implies{\tt{(6x + 5x) + ({38}^{\circ} + {90}^{\circ} + {8}^{\circ}) = {180}^{\circ}}}}\\\\\quad{\implies{\tt{(11x) + ({128}^{\circ} + {8}^{\circ}) = {180}^{\circ}}}}\\\\\quad{\implies{\tt{(11x) + ({136}^{\circ}) = {180}^{\circ}}}}\\\\\quad{\implies{\tt{11x + {136}^{\circ} = {180}^{\circ}}}}\\\\\quad{\implies{\tt{11x = {180}^{\circ} - {136}^{ \circ}}}}\\\\\quad{\implies{\tt{11x = {44}^{ \circ}}}}\\\\\quad{\implies{\tt{x = \dfrac{44}{11}}}}\\\\\quad{\implies{\tt{\underline{\underline{x = 4}}}}}\end{gathered}[/tex]
Hence, the value of x is 4.
Now, we know the value of x. So, calculating the mission angles of triangle :
