Answer:
1
Step-by-step explanation: Plug in the value of 2 into both equations and then just divide as said.
Answer:
Angle ADC = 180°-60° = 120°
Step-by-step explanation:
We could actually do without the additional detail pertaining to 75°. However, we could find angle CDB by difference. The solution would be 120°-75° = 45°. But this is not anymore needed by the problem because it is not asked. I guess the 75° is just a distraction.
Answer:
x= 116/17
Step-by-step explanation:
5x+192−321+13=−12x
Step 1: Simplify both sides of the equation.
5x+192−321+13=−12x
5x+192+−321+13=−12x
(5x)+(192+−321+13)=−12x(Combine Like Terms)
5x+−116=−12x
5x−116=−12x
Step 2: Add 12x to both sides.
5x−116+12x=−12x+12x
17x−116=0
Step 3: Add 116 to both sides.
17x−116+116=0+116
17x=116
Step 4: Divide both sides by 17.
17x/17=116/17
x = 116/17
