X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
Answer:
Base = 24 ft; height = 47 ft
Step-by-step explanation:
The formula for the area of a triangle is
A = ½bh
Let x = the base. Then
2x - 1 = the height

We reject the negative value, so x = 24 ft
Base = x = 24 ft
Height = 2x - 1 = 2(24)-1 = 48 - 1 = 47 ft
Check:
564 = ½ × 24 × 47
564 = 564
OK
<em>take two points</em> : (-4, 3), (3, 1)
<u>where</u> (x1, y1), (x2, y2)
<u>Insert the following values</u>
