Question

In the following figure find the unknown angled a and b, if l || m.

Answer 1

Simplifying 3x + -2y = 19 Solving 3x + -2y = 19 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. 3x + -2y + 2y = 19 + 2y Combine like terms: -2y + 2y = 0 3x + 0 = 19 + 2y 3x = 19 + 2y Divide each side by '3'. x = 6.333333333 + 0.6666666667y Simplifying x = 6.333333333 + 0.6666666667y

Answer 2

Answer:

Step-by-step explanation:

c 110° (corresponding angles are

equal)

now, aᵒ+c=180°

aᵒ+110°=180°

a=180°-110°

aᵒ=70°

now aᵒ+40°+x=180° (angle sum property

of triangle)

70°+40°+x=180°

110°+x=180°

x=180-110°

x=70°

now, xᵒ+b=180°

70°+b=180°

b=180°-70°

b=110°

values of and b are 70°and 110°
