The measures of the three angles of a triangle are given by 2x + 6, x, and 3x.
What is the measure of the largest angle?

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.

The largest angle is 87 degrees.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
