Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
Hello there!
the solutions to this system of inequalities are every point in the blue area. In order to figure out if each of those choices are solutions, just graph the points, and if they are in the blue, they are solutions.
Using this method, you get A and C as your answers because they are in the blue region.
I really hope this helps!
Best wishes :)
Answer:
x₁ = √15
x₂ = - √15
Step-by-step explanation:
x² - 15 = 0
x² = 15
x = ±√15
x₁ = √15
x₂ = - √15
