To solve this problem we will use the following property of triangles:
So if we are given the angles a and b of a triangle, the third side c, must be:1) The angles are a =
[tex]\begin{gathered} a+b+c=180^{\circ}, \\ c=180^{\circ}-a-b\text{.} \end{gathered}[/tex]
[tex]c=180^{\circ}-48^{\circ}-62^{\circ}=70^{\circ}\text{.}[/tex]
i. 70°
2) a = 48° and b = 62°, so we have:
[tex]c=180^{\circ}-71^{\circ}-36^{\circ}=73^{\circ}.[/tex]
h. 73°
3) a = 41° and b = 86°, so we have:
[tex]c=180^{\circ}-41^{\circ}-86^{\circ}=53^{\circ}.[/tex]
j. 53°
4) a = 61° and b = 88°, so we have:
[tex]c=180^{\circ}-61^{\circ}-88^{\circ}=31^{\circ}.[/tex]
d. 31°
5) a = 55° and b = 92°, so we have:
[tex]c=180^{\circ}-55^{\circ}-92^{\circ}=33^{\circ}.[/tex]
b. 33°
