Answer: 20.058
Step-by-step explanation:
401.16 x 0 05
= 20 058
Answer:
20 units
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are equal in length.
Equate any 2 sides and solve for x
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
hence
4x = 4 × 5 = 20
3x + 5 = (3 × 5) + 5 = 15 + 5 = 20
7x - 15 = (7 × 5) - 15 = 35 - 15 = 20
The lengths of the sides are 20 units
10. angle APB = (1/2) arc AB
108 = (1/2) arc AB
multiply both sides by 2 to clear the fraction
216 = arc AB
11. Area of regular Octagon s = 5 in
A = (P * apothem)/2 => => If you divide the octagon into 8 triangles, the apothem is the perpendicular height of the triangle.
A = (5 * 8 * 6)/2
A = 120 in^2
Area of regular Hexagon s = 5 in
A = (5 * 6 * 4.3)/2
A = 129 in^2
<span>three consecutive even integers are x, x+2 and x+4
x + x+2 + x+4 = 66
3x + 6 = 66
3x = 66-6
3x = 60
x = 60/3
x = 20 </span>← first integer
<span>
x + 2 = 20 + 2 = 22 </span>← second integer
x + 4 = 20 + 4 = 24 ← third integer
