Answer 2

Answer:

The angle ACB is 9 degrees.

Step-by-step explanation:

To solve this problem we just need to observe the point B, which has two angles and both of them are on a straight angle, this means that the sum of angle ABC and CBD is 180, that is

$\angle ABC + \angle CBD = 180\°$

We know that $\angle =29\°$, then

$\angle ABC+29=180\\\angle ABC=180-29=151$

Now, in the triangle ABC, we know that all three angles must sum 180

$\angle CAB + \angle ABC + \angle BCA = 180\\20+151+ \angle BCA = 180\\\angle BCA = 180-20-151\\\angle BCA = 9=\angle ACB$

Therefore, the angle ACB is 9 degrees.
