Question

Calculate the perimeter od triangle QRS

Answer 1

17*2+30=64

Explanation:

Begin by splitting the triangle in half, we get triangle QbS...

then use the Pythagorean theorem we get following equation:

a²+line(b to S)²=line(Q to S)²

`(3 √(7) )^(2) + 15 {}^(2) = x {}^(2)`

the result of x will be rounded to 17 since its around 16.9. then we'll add all of the sides of the big triangle QRS

17+17+30=64
