Answer:
40⁰, 60⁰, and 80⁰
Explanation:
We know that in every triangle the angles add up to 180⁰. Remember that?
So those 3 terms have to add up to 180:
2x + 3x + 4x = 180
Combine like terms:
9x = 180
Divide by 9:
x = 20⁰
But we're not done yet, because each of the terms has a multiplier of x, so:
- one angle is 40⁰
- one is 60⁰
- one is 80⁰
Let's check our work: do those add up to 180⁰?
40 + 60 + 80 = 180
