Hi, Since 1 Qn per post is allowed, you may post the Question 28 onwards separately,
Here; the answer to the Q28
Now, ABC the whole ange has 2 angles ABD and DBC which are equal.
Given the fact that 5x=3x+10
So, 2x=10, x=5
Therefore, ABC angle = 5x+3x+10 = 8x+10 = 40+10 =50.
Measure of angele ABC = 50 degrees.
