If m ABC = 80°, what is m DBC? Justify your reasoning.

0

Using the Angle Addition Postulate, 20+ m2DBC

11

DBC = 60° using the subtraction property of equality.

EE

Using the Angle Addition Postulate, 20 + 80

DBC. So, m DBC = 100° using the addition property of equality.

0

Using the addition property of equality, 20 + 80

0

Using the subtraction property of equality, 80

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
