The table to complete the proof is as follows

Equation                                                              statement

1. m∠ABD = 60°, m∠DBC=40°                               Given

2. m∠ABD + m∠DBC = m∠ABC               Angle Addition Postulate

3. 60° +  40° = m∠ABC                           Substitution Property of Equality

4. 100° = m∠ABC                                                  Simplifying

5. ∠ABC is an obtuse angle.                       greater than 90 degrees

6. △ABC is an obtuse triangle.                Definition of obtuse triangle

(MATH) What is the reason for each step in the solution of the inequality?
Rama09 [41]

Step-by-step explanation:

Inequalities are solved just like equations the only difference is that the inequality sign has to be considered.

We are writing the steps with reason

So,

1. Given

-38-3(x+5)>6x-17

2. Distributive property:

-38-3x-15>6x-17

3. Combine like terms

-3x-53>6x-17

4. Subtraction property of order

-3x-53-6x>-17

-9x-53> -17

5. Addition property of order

-9x> -17+53

-9x>36

6. Division property of order

x
