Check the picture below.
now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².
It’s 30 because they are vertical angles which means both sides are congruent

The answer is 8 1/4 hours
Eliminate x's
multiply 2nd equation by -2 ad add to first
2x+3y=9
<u>-2x-10y=-16 +</u>
0x-7y=-7
-7y=-7
divide by -7
y=1
sub back
2x+3y=9
2x+3(1)=9
2x+3=9
minus 3
2x=6
divide 2
x=3
x=3
y=1
(x,y)
(3,1)
