Hey there!
BOD is a 90 degrees angle. Make an equation for that angle. 15+12+x=90. Simplify this to 27+x=90. You need to isolate x, so subtract 27 on each side to get x=63. C is the answer.
I hope this helps!
Replace x any with their values:
3(-4) + 7(6) -12
Simplify:
-12 + 42 -12
Solve:
-12 + 42 -12 = 42
