There is a string of red and blue lights strung around a window. The red lights blink every 3 seconds٫ and the blue lights blink every 5 seconds. How many times will they blink at the same time in one minute?

the correct answer is the second option

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

i think it’s a i believe
