Let the angles be 2x, 3x, and 4x. Then, 2x + 3x + 4x = 180 degrees. Therefore, 9x = 180, x = 20. The largest angle is 4x = 80 degrees.

Q
Q: If the angles of triangle JKL are in the ratio 2:3:4, what is the measure of the largest angle? (2023)
Solution:
Let the angles be 2x, 3x, and 4x. Then, 2x + 3x + 4x = 180 degrees. Therefore, 9x = 180, x = 20. The largest angle is 4x = 80 degrees.
Steps: 9
Show Steps
Step 1: Understand that the angles of triangle JKL are in the ratio 2:3:4.
Step 2: Let the angles be represented as 2x, 3x, and 4x, where x is a common multiplier.
Step 3: Add the angles together: 2x + 3x + 4x.
Step 4: Simplify the equation: 2x + 3x + 4x = 9x.
Step 5: Set the sum of the angles equal to 180 degrees (the total degrees in a triangle): 9x = 180.
Step 6: Solve for x by dividing both sides by 9: x = 180 / 9.
Step 7: Calculate x: x = 20.
Step 8: Find the largest angle by calculating 4x: 4x = 4 * 20.
Step 9: Calculate the largest angle: 4x = 80 degrees.
