The difference of complementary angles is 10⁰. Find the measures of the angle.​

40° and 50°

Step-by-step explanation:

Complementary angles sum to 90°

let x be one angle then x - 10 is the other, their sum is

x + x - 10 = 90

2x - 10 = 90 ( add 10 to both sides )

2x = 100 ( divide both sides by 2 )

x = 50

Then angles are 50° and 50° - 10° = 40°

50° and 40°

Step-by-step explanation:

Since complementary angles are 90°, the angles combined have to equal to 90.

50 - 40 = 10

40 + 10 = 50

50 + 40 = 90

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
