Find the measures of the missing angles.​

m∠1 = 51

m∠2 = 61

m∠3 = 29

Step-by-step explanation:

Hey There!

So the first angle that we want to find is angle 1

They have given us 2 angles and if  you didnt know all of the angles in a triangle will add up to equal 180. So if given 2 angles all we have to do is subtract the given angles from 180 and we get the 3rd angle

180-68-61=51 so m∠1 = 51

Now we want to find angle 2 and angle 2 is vertical to the angle that is equal to 61. If you didnt know vertical angles are congruent to each other therefore m∠2 = 61

Now we want to find angle 3. We know that angle 2=61 and the square on the bottom right of the triangle indicates that its a right angle so its equal to 90

Now like last time we want to subtract the given angles from 180 to find m∠3

180-90-61=29 so m∠3=29

hope this helps :)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

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.
