The perimeter of any figure, is all its sides summed up
now, notice the picture below, using the 30-60-90 rule, that's "x"
now, get the other sides, since you know what "x" is, and sum them up, that's the perimeter
Answer:
A
Step-by-step explanation:
for a right angled triangle, the sum of the square of the two sides should be equal to the square of the hypotenuse. If this rule does not hold, the dimensions do not represent the side of a right angled triangle.
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
4² + 10² ≠ 16²
6² + 12² = 13²
7² + 24² = 25²
8² + 15² = 17²
Steps to solve:
x/3 + 1/4 = 1/3
~Subtract 1/4 to both sides
x/3 = 1/12
~Multiply 3 to both sides
x = 1/4
Best of Luck!
