Answer:
x = 28°, ∠ABC = 57°
Step-by-step explanation:
∠ABD = 2x+1
∠BCD = 33°
∠ABD = 90° (right angle)
which means that
∠ABC + <CBD = 90° (In the middle of ∠ABD)
Then, we can substitute to the equation to find x
(2x+1) + 33° = 90°
(2x+1) = 57°
2x = 56°
x = 28°
after finding x, we can find ∠ABC:
∠ABC = 2(28) + 1 = 57°
I hope this helps, have a great day! :)
