Two supplementary angles differ by 34. Find the angles.​

Answers

Answer:

x=107,y=73 is ur answer

Step-by-step explanation:

let two angles be x & y

x-y=34(given)

x=34+y................1

x+y=180(supplementary)

putting the value of x

34+y+y=180

2y=180-34

y=146/2=73

:.y=73

putting the value of y in equation 1

x=34+73=107

:.x=107

Answer:

73° and 107°

Step-by-step explanation:

Mark one of the angles as x

then the other angle is (x + 34)

Two angles are called supplementary when their measures add up to 180 degrees.

So the sum of those angles is always 180°

x + (x + 34) = 180

2x + 34 = 180

2x = 180 - 34

2x = 146

// divide both sides by 2

x = 73°

Now find the other angle

x + 34 = 73 + 34 = 107°

Suppose you are facing north, each time you turn, you are going to turn 90 degrees. If you turn 2 times to the right, 1 time to the left, 3 times to the right, 2 times to the right, and 1 time to the left, which way are you now facing?

Answers

Answer:

East

Step-by-step explanation:

Starting position = North

Condition = each time you turn, you are going to turn 90 degrees

Using the image attached as a guide;

If you turn 2 times to the right

- Turning the first time to the right changes the direction to East

- Turning the second time to the right changes the direction to South

1 time to the left

- Turning once to the left changes the direction to East

3 times to the right

- Turning the first time to the right changes the direction to South

- Turning the second time to the right changes the direction to West

- Turning the second time to the right changes the direction to North

2 times to the right

- Turning the first time to the right changes the direction to East

- Turning the second time to the right changes the direction to South

1 time to the left

- Turning once to the left changes the direction to East
