If angle ABD is 79 what is angle ABC and DBC DBC (5x+4) ABC (8x-3)?

Evidently, ABC+DBC = ABD

So,

5x+4 + 8x-3 = 79
x=6

so plug in that to the expressions given.

To find the measures of angles ABC and DBC, we need additional information or equations relating these angles. The given value of angle ABD being 79 degrees alone is not sufficient to determine the measures of angles ABC and DBC.

If we have another equation or angle measurement that can help us find the values of angles ABC and DBC, please provide that information, and I will be happy to assist you further.
