<h3>
Answer:</h3>
2x = 60
3x = 90
x = 30
<h3>
Step-by-step explanation:</h3>
All triangles have 3 angles that add up to 180 degrees. We can use the information to create an equation.
Finding x
First, add all of the angles together and set them equal to 180
Next, combine like terms
Finally, divide both sides by 6
Solve For Missing Angles
Now that we have x, we can solve from each of the missing angles. Do this by plugging in 30 for the x-values.
2x
3x
x
We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.
Answer:
x = 30°
The angles:
- 2x° = 60°
- 3x° = 90°
- x° = 30°
Step-by-step explanation:
Hello!
The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.
Solve the equation:
- 2x° + 3x° + x° = 180°
- 6x° = 180°
- x° = 30°
We can replace 30° for all the angles.
The measures are:
- 2(30°) = 60°
- 3(30°) = 90°
- 1(30°) = 30°
