The measure of a is 20° greater than the measure of b. the two angles are complementary. find the measure of each angle. the m a is ° and m b is °.

The m∠A is 55° and m∠B is 35°. Hope this helps

Step-by-step explanation:

Step 1: m∠A + m∠B=90°

Step 2: m∠A + (m∠A − 20°)=90°

Step 3: m∠A + (m∠A − 20°)=90°

+20°=+20°Add 20° to both sides.

m∠A + m∠A=110°

2(m∠A)=110°Divide both sides by 2.

m∠A=55°

Step 4: m∠A + m∠B=90°

55° + m∠B=90°Substitute 55° for m∠A.

m∠B=35°

step-by-step explanation:

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.
