Answer:
see below
Explanation:
We can find <C by adding all three angles in a triangle
<DBC + <C + <BDC = 180
30+ <C + 90 = 180
Combine like terms
120 + <C = 180
Subtract 120 from each side
120-120 + <C = 180-120
<C = 60
We can find <ABD by adding all three angles in a triangle
<ABD + <A + <BDA = 180
<ABD + 35 + 90 = 180
Combine like terms
< ABD +125 = 180
Subtract 180 from each side
< ABD +125-125 = 180-125
<ABD = 55
<ABC = <ABD + <DBC
= 55 + 30
< ABC = 85
