The legs are 12 cm each, so the hypotenuse is√(144+144)=12√2☺☺☺☺
Steve = S , Tom = T
1) S+T = 7777
2) S= 1414 + 2T
put 2) in 1)
1414+2T + T = 7777
1414 +3T = 7777
3T = 6363
so T = 2121
then Steve sold 1414+2(2121) = 1414+4242=5656 tickets
while Tom sold 2121 tickets

Answer:
X=17
Angle K=110 degrees
Angle L= 70 degrees
Angle M= 110 degrees
Angle N= 70 degrees
Explanation:
6x + 8 + 2x +36=180
8x + 44= 180
8x = 136
X = 17
6(17)+8
102+8
110
2(17)+ 36
34+36
70
110 + ? =180
180-110= 70
70 + ?=180
180-70=110
