If L is parallel to M, find the values of x, y, and all 3 angles.
lesya [120]

Answer:

8x - 14 = 5x + 34 (alternate exterior angles)

8x - 5x = 34 + 14

3x = 48

x = 48/3

x = 16

5y + 16 + 8x - 14 = 180 (linear pair)

5y + 16 + 8(16) - 14 = 180

5y + 16 + 128 - 14 = 180

5y + 130 = 180

5y = 180 - 130

5y = 50

y = 50/5

y = 10

∠ (8x - 14) = 114   [(8 × 16 -14)=114]

∠ (5x + 34) = 114  [(5 × 16 +34)=114]

∠ (5y + 16) = 66   [(5 × 10 +16)=66]

hope this helps you!

Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined
Annette [7]

Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .

<u>Step-by-step explanation:</u>

Here we have to Find x so that the two points are on the line with the given slope (1,-1) and (x,7): undefined . Let's find out:

We know that for any two points given as P(x_1,y_1),Q(x_2,Y_2)  slope of line is determined by :

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

According to question we have two points as  P(1,-1),Q(x,7) ∴

⇒ Slope = \frac{y_2-y_1}{x_2-x_1}

⇒ Slope = \frac{7-(-1)}{x-1}

But slope is undefined which is only possible when denominator is zero i.e.

⇒ x-1=0

⇒ x=1

Therefore , Value of x for which the two points are on the line with the given slope (1,-1) and (x,7): undefined is x=1 .
