Please help me with this question if you can

Step-by-step explanation:

the 3rd angle = 4x+17 because of vertical angles

4x+17 + x+23 + 80 = 180 sum of interior angles of a triangle

5x +40 = 100

5x = 60

x = 12

angle A = x + 23 = 12 +23 = 35

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
