Find The Value of X:<br> A= 12<br> B= 16<br> C= 21<br> D= 24
Dmitriy789 [7]

Answer:

x = 21

Step-by-step explanation:

The 2 angles form a straight angle and are supplementary, thus

7x + 9 + 2x - 18 = 180, that is

9x - 9 = 180 ( add 9 to both sides )

9x = 189 ( divide both sides by 9 )

x = 21

Find all points having an x coordinate of 5 whose distance from the point (2,2) is 5.
stepan [7]

Answer:

(5,6) , (5,-2)

Step-by-step explanation:

Let the required point be P(5,y).

Its distance from (2,2) is 5 units.

So, (5-2)^{2} + (y-2)^{2} = 25.

So, 3^{2} +  (y-2)^{2} = 25.

  9 +  (y-2)^{2} = 25.

   (y-2)^{2} = 16

    Two cases are possible for now

case 1 : y-2 = 4 .

            y = 6

required point will be (5,6)

case 2 : y - 2 = -4.

              y = -2.

required point will be (5,-2).

Two points are possible : (5,6) , (5,-2).
