Plz help plz plz only 4 question​

c.

x = 130° (exterior opposite angles)

y + x = 180° (linear pair of angles)

=> y + 130° = 180°

=> y = 180° - 130°

=> y = 50°

d.

z = 100° (corresponding angles)

a = 100° (corresponding angles)

x + 100° = 180° (linear pair of angles)

=> x = 180° - 100°

=> x = 80°

y = x (interior opposite angles)

=> y = 80°

b = y (corresponding angles)

=> b = 80°

g.

a = 112° (vertically opposite angles)

b = a (interior opposite angles)

=> b = 112°

x = 78° (vertically opposite angles)

x + y = 180° (interior angles on the same side of transversal)

=> 78° + y = 180°

=> y = 180° - 78°

=> y = 102°

h.

f = 120° (vertically opposite angles)

e = 105° (vertically opposite angles)

c = 120° (corresponding angles)

d = 105° (corresponding angles)

a + d = 180° (linear pair of angles)

=> a + 105° = 180°

=> a = 180° - 105°

=> a = 75°

b + c = 180° (linear pair of angles)

=> b + 120° = 180°

=> b = 180° - 120°

=> b = 60°

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

a is the right answer
