Answer:
x = 85
y = 65
Step-by-step explanation:
By interior angle sum property of a triangle.
y° + 25° + 90° = 180°
y° + 115° = 180°
y° = 180° - 115°
y° = 65°
y = 65
By remote interior angle theorem of a triangle:
x° = y° + 20°
x° = 65° + 20° (since y = 65)
x° = 85°
x = 85
Only one set of factors for 26, which is 2 by 13

Step-by-step explanation:
Answer:
$110, $44
Step-by-step explanation:
Let x = the total cost to Stefan
Jim buys for:
bicycle: $138
helmet: $16
total: $138 + $16 = $154
Jim's price of $154 is 140% of Stefan's cost, x.
154 = 140% × x
1.4x = 154
x = 110
Stefan spent $110.
Stefan's profit:
$154 - $110 = $44
