Answer:
x=19
Step-by-step explanation:
●Alternate angles are equal
therefore, angle WYZ= angle YWX
2x= angle YWX
●Angles within a triangle sum up to 180 degrees
=3x-5+2x+90=180
▪︎group like terms
=3x+2x+90-5=180
=5x+85=180
▪︎send all x terms to one side of the equation
=5x=180-85
=5x=95
▪︎divide both side by the coefficient of x ; 5
=x=19
