Find the value of y. (3y+1) (8x-61) (6x-13)

y = 16

Step-by-step explanation:

you can set 6x - 13 and 8x - 61 equal to each other because they are Alternate-Exterior angles and are congruent; this will give you the value of 'x'

6x - 13 = 8x - 61

-13 = 2x - 61

2x = 48

x = 24

3y + 1 + 8x - 61 = 180   (they form a straight line)

substitute 24 for 'x'

3y + 1 + 8(24) - 61 = 180

3y + 132 = 180

3y = 48

y = 16

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
