x = 8
Step-by-step explanation:
The sum of the measures of two complementary angles is 90°.

Answer:
10 miles
Step-by-step explanation:
Given: Boat goes
hours with 8 mph (i)
Boat goes
hours with 12 mph (ii)
Now, lets find out distance separately to get total distance.
Formula for finding distance is
D= 
D=
(i)
D= 
∴ D1= 6 miles (i)
D=
(ii)
∴D2= 4 miles (ii)
To find total distance, we will add d1 and d2
Total distance = 
∴ Total distance = 
= 10 miles is the total distance covered by boat in all this time.
