So lets call the angles x and y
x is 2 more than y
x=2+y
complementary means adds to 90 so '
x+y=90
we have
x=2+y
x+y=90
subsitute 2+y for x
2+y+y=90
2+2y=90
subtract 2
2y=88
divid 2
y=44
subsitute
x=2+y
x=2+44
x=46
angles are 44 and 66
Answer:
4250 km
Step-by-step explanation:
If we convert 25/6 into a mixed fraction, we get 4 1/6. Since we already know the plane goes for four hours already, we can multiply 1020 km x 4. That would give us 4080. Now that we converted the equation into a mixed fraction, we also know that the plane goes for an extra 1/6 hour. We divide 1020/6 because it is a sixth of an hour and the plane can travel 1020 in an hour. We get 170 km for 1/6 of an hour.
4080km + 170km= 4250 km
