If m ABC = 80°, what is m2DBC? Justify your reasoning. O Using the Angle Addition Postulate, 20+ m2DBC = 80. So, m2DBC = 60° using the subtraction property of equality
O Using the Angle Addition Postulate, 20 + 80 = m_DBC. So, m DBC = 100° using the addition property of equality.
O Using the addition property of equality, 20 + 80 = 100, so mzDBC = 100°.
O Using the subtraction property of equality, 80 - 20 = 60, SO MZDBC = 60°

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
