Answer:
-2.5
I got -2.5 as slope because slope is equal to rise over run so that means
the equation would turn out as -29+9/15-7=-20/8
-20/8=-2 4/8,-2 1/2,1/2=0.5,so the answer turns into -2.5
The answer is 4+5+6=15.Hope that helps. :)
Answer:
∠AOB = 120°
∠BOC = 140°
∠BOD = 140°
Step-by-step explanation:
First, find X !
Full circle is 360°
360 = (2x + 80) + (5x + 40) + 4x + x
360 = 12x + 120
240 = 12x
x = 20°
Substitute the X
∠AOB ≡ (2x + 80) =
(2(20) + 80) = 120°
∠BOC ≡ (5x + 40) =
(5(20) + 40) = 140°
∠BOD = ∠AOB + ∠DOA ≡
120 + x = 120 + 20 = 140°
