Given O A ‾ ⊥ O C ‾ OA ⊥ OC start overline, O, A, end overline, \perp, start overline, O, C, end overline m ∠ B O C = 6 x − 6 ∘
m∠BOC=6x−6 ∘ m, angle, B, O, C, equals, 6, x, minus, 6, degrees m ∠ A O B = 5 x + 8 ∘ m∠AOB=5x+8 ∘ m, angle, A, O, B, equals, 5, x, plus, 8, degrees Find m ∠ B O C m∠BOCm, angle, B, O, C:
What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.
Another way I like to think about this is the two minus symbols combine together to form a plus sign.
