1. 0.5x+3.5
Slope: 0.5
y-intercept: (0,3.5)
x: (-7,0)
y: (0,3.5)
It's a half of an equilateral triangle because their angles measure 30° and 60° (an equilateral triangle has 3 angles of 60°)
So x=(2h/√3)/2=h√3=27√3≈15.6
Answer: The answer for this is x=12
Answer:
x = 8
Step-by-step explanation:
All sides are equal in terms of symmetry, such as the 5 and 5 opposite the angle 120 that repeats itself at the centre 3 times
