Answer:
140°
Step-by-step explanation:
The value of supplement is 40 and X. We know that the sum of the sumplementary angles is 180. Therefore ,
=> x + 40° = 180°
=> x = 180° - 40°
=> x = 140°

=Mr.Lehmans hourly rate for labor is 20$
=30+40=70-50=20
Answer/Step-by-step explanation:
1. m<UTV = m<RTS = 85°
Reason: Definition of vertical angles.
Vertical angles are congruent to each other. m<UTV and m<RTS are vertical angles pair.
2. m<R + m<S + m<RTS = 180°
Reason: sum of interior angles of a ∆.
3. 3x + 2x + 85° = 180°
Reason: Substitution
4. x = 19
Reason: Algebra
Solving the equation algebraically, we would have the following:
3x + 2x + 85° = 180°
Add like terms
5x + 85 = 180
5x = 180 - 85 (subtraction property of equality)
5x = 95
Divide both sides by 5
x = 19
