(2y + 50)" (7x - 248)<br> (5y - 17) (x +44)°<br> Find the value of x and y.
Sveta_85 [38]

Answer:

x = 48

y = 21

Step-by-step explanation:

To find the value of x and y, using the definition of supplementary angles, create an equation to find x and y as follows:

Finding y:-

(2y + 50) + (5y - 17) = 180 (supplementary angles definition)

Solve for y

2y + 50 + 5y - 17 = 180

Collect like terms

2y + 5y + 50 - 17 = 180

7y + 33 = 180

7y + 33 - 33 = 180 - 33

7y = 147

\frac{7y}{7} = \frac{147}{7}

y = 21

Finding x:-

(7x - 248) + (x + 44) = 180 (supplementary angles definition)

Solve for x

7x - 248 + x + 44 = 180

Combine like terms

8x - 204 = 180

8x - 204 + 204 = 180 + 204

8x = 384

\frac{8x}{8} = \frac{384}{8}

x = 48

A is (-2,1)
valkas [14]

1) in order to solve this problem you must to obtain The value of K,  for it you know by definition  that the  horizontal slope  of the side BC  is zero ,

then m = Y2-Y/X2-X1,   0 = 5-K/4-6⇒0 = 5-K⇒K = 5

known this value for K   you ca find the equation of thE line that pass through  A and C

2) Following the same procedure in first place you calculate the slope with the points A(-2,1) Y C ( 4,5)

m= 5-1/4-(-2) = 2

now with any point  A  or C and the slope you obtain the line

A(-2,1)

y-y1 = m (x-x1) ,   Y-1= 2(X-(-2)⇒Y-1= 2X+4⇒Y=2X+4-1⇒Y =2X+3
