4) Find the value of x in the given diagram. (3 points)
Oxana [17]

Answer:

113

Step-by-step explanation:

The given shape has 6 angles so it's a hexagon and the sum of interior angles in a hexagon is = 720

To find the the value of x we need to add all given values up and subtract it from 720:

88 + 142 + 105 + 136 + 136 + x = 720

607 + x = 720 subtract 607 from both sides

x = 113

If the slope of line l is x, and the slope of line m is x+2, and l⊥ m, what is x?
salantis [7]

Answer:

The answer to your question is:  x = -1

Step-by-step explanation:

Data

slope of l = x

slope of m = x +2

they are ⊥

Process

If they are ⊥, then,     x + 2  = - 1/x

                                  x(x + 2) = -1

                                  x² + 2x = -1

                                  x² + 2x + 1  = 0

                                 (x + 1)² = 0

                                 x + 1 = 0

                                x = -1
