NEED HELP ASAP!! Our teacher never taught my class this and its on our homework. someone please help!!! i'll give brainliest to whoever is right

Answer:m∠ABX = (12+4y)°equation: (12+4y) +y = 92m∠ABX = 76°m∠CBX = 16°Step-by-step explanation:The reason this is titled "Mathematical Connections" is because you're supposed to draw upon all of the things you have learned about angles and equations and put them together to solve this problem. No problem-specific teaching should be necessary.__The words and diagram tell you that ...   m∠ABX + m∠CBX = 92°They also tell you that ...   m∠CBX = y°.The words tell you that m∠ABX = 12° + 4(m∠CBX). Since m∠CBX = y°, this means ...   m∠ABX = (12 +4y)° . . . . . this expression fills the box on the diagram__So, we have expressions involving y for each of the parts of angle ABC. We can substitute those expressions into the angle sum equation to get   (12 +4y) + (y) = 92 . . . . . . dropping the degree symbol, using only numbers __Using what you know about algebra and 2-step equations, you can solve this to find the value of y.   5y +12 = 92 . . . . . simplify   5y = 80 . . . . . . . . subtract 12   y = 16 . . . . . . . . . . divide by 5This value can be substituted back into the expressions for angle measure:   m∠CBX = y° = 16°   m∠ABX = (12+4y)° = (12 +4·16)° = 76°
