Sagot :
Answer:
D. 2x+75=180
Step-by-step explanation:
Given:
This figure gives us 180 degrees of angles.
Calculate the angle of x in the figures according to the term x on one side of the equation.
The angle relationship should be represented by 2x.
2x+75=180
First, subtract by 75 from both sides.
2x+75-75=180-75
Solve.
Subtract the numbers from left to right.
180-75=105
2x=105
Divide by 2 from both sides.
2x/2=105/2
Solve.
Divide the numbers from left to right.
105/2=52.5
x=105/2=52.5
- Therefore, the correct answer is "D. 2x+75=180".
