Answer:
x=13 y=54
Step-by-step explanation:
9x-7=7x+19
2x=26
x=13
180-(9*13 -7)=y+16
180- 110 = y+16
70=y+16
54=y
Answer:
x = 13, y = 54
Step-by-step explanation:
( 9x - 7 ) and ( 7x + 19 ) are vertically opposite angles. Vertically opposite angles are equal since line m and n are parallel.
9x - 7 = 7x + 19
9x - 7x = 19 + 7
2x = 26
x = 26 / 2
x = 13
7x + 19
= ( 7 ) ( 13 ) + 19
= 91 + 19
= 110
( 7x + 19 ) and ( y + 16 ) are linear pair angles. Sum of linear pair angles is 180,
y + 16 + 7x + 110 = 180
y + 16 + 110 = 180
y + 126 = 180
y = 180 - 126
y = 54
