Answer:
Solution. Let x be any number such that the three angles are (3x)°, (1x)°, and (2x)°. We know, the sum of the angles of a triangle is 180°. The measure of the largest angle is 90°
Answer:
90⁰
Explanation:
Let the angles be 3x, x and 2x.
3x+x+2x=180⁰ (Angle sum property of triangle)
6x=180⁰
x=30⁰
Largest angle = 3x = 3×30 = 90⁰
