Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.
Combine like terms (all terms with an x) on the left side.
Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.
x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.
Substitute 29 for x in the angle measures.
- 2x+6= 2(29)+6=58+6=<u>64</u>
- x=<u>29</u>
- 3x= 3(29)=<u>87</u>
<u></u>
The largest angle is 87 degrees.
