A person walks 8blocks east, then 4 blocks north, 12 blocks west and 4 blocks south, at this point how many blocks from her star
Setler79 [48]

Answer:

4 Blocks.

Step-by-step explanation:

You start out going 8 east so that's 4.

Then you got 4 north as well so that's 12 because 8 + 4 = 12

then they walk 12 blocks west. Now they are in the position of 4 North and 4 West.

Next they go 4 blocks south. Since they went for blocks North first and now they go 4 blocks south and they are already on the fourth block to the west.

When they are at 4 North and 4 South the just travel to the original position but 4 blocks to the west.

Sorry if you don't understand the explanation. It's kinda difficult to explain.

Please help 50 points
yulyashka [42]

Answer:

m∠RQS = 109°

Step-by-step explanation:

<u>Angles on a straight line sum to 180°</u>.

Therefore:

⇒ m∠RQS + m∠SQT = 180°

⇒ (15x + 4) + (10x + 1) = 180

⇒ 15x + 4 + 10x + 1 = 180

⇒ 15x + 10x + 4 + 1 = 180

⇒ 25x + 5 = 180

⇒ 25x + 5 - 5 = 180 - 5

⇒ 25x = 175

⇒ 25x ÷ 25 = 175 ÷ 25

⇒ x = 7

Now that we have found the value of x, substitute this into the expression for m∠RQS:

⇒ m∠RQS = 15(7) + 4

                  = 105 + 4

                  = 109°
