Answer:
[tex]{ \tt{(3x + 5) + (7x + 5) = 180}} \\ \\ { \tt{(3x + 7x) + (5 + 5) = 180}} \\ \\ { \tt{10x + 10 = 180}} \\ \\ { \tt{10x = 170}} \\ \\ { \boxed{ \tt{x = 17}}}[/tex]
• Angle 1 = Angle 4
[tex]{ \tt{ \angle 1 = \angle 4 = 3x + 5}} \\ \\ { \tt{\angle 1 = \angle 4 = (3 \times 17) + 5}} \\ \\ { \boxed{ \rm{\angle 1 = \angle 4 = 56 \degree}}}[/tex]
• Angle 2 = Angle 3
[tex]{ \tt{\angle 2= \angle 3 = 7x + 5}} \\ \\ { \tt{\angle 2 = \angle 3 = (7 \times 17) + 5}} \\ \\ { \boxed{ \rm{\angle 2 = \angle 3 = 124 \degree}}}[/tex]
