It will move but won't change shape or size.
-2,2 is the answer hoped it helped :)
If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal. So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.
Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer
278 divided by 59 is 4.712, which can be rounded to 5
the answer is d. 5
