Answer:
[tex]x=\frac{3}{7}[/tex] Degrees
Step-by-step explanation:
3x+15°+8x+7°+3x-16°
bringing the like terms together . Like terms are those terms which contains the same variable. Hence here we have 3x , 8x and 3x our like terms and the constant terms are also like terms
3x+8x+3x+15°+7°-16°
adding the similar terms and simplifying the constant terms
14x=22°-16°
14x=6°
Dividing both the sides by 14
[tex]\frac{14x}{14}=\frac{6}{14}[/tex]
[tex]x=\frac{3}{7}[/tex]
