Step-by-step explanation:
<4 and <5
<4 and <1
The angles in both the pairs are adjacent to each other and make 180° together
Let us say that:
x = hours worked by Wolfgang
y = hours worked by Heinrich
So that:
x = y + 10
14 x + 12 y = 3520
By combining the two equations:
14 (y + 10) + 12 y = 3520
14 y + 140 + 12 y = 3520
26 y = 3380
y = 130 hours
x = y + 10 = 140 hours
<span>So Wolfgang worked 140 hours while Heinrich worked 130
hours.</span>
