Answer:
70% of the meeting is left.
Step-by-step explanation:
Hi, to answer this question, first, we have to convert the hours to minutes.
Since 1 hour = 60 minutes
For 2 hours:
1 /60 = 2/x
x = 2 (60)
x = 120 minutes
So, a scout meeting last 120 minutes (2 hours)
36 minutes already spent.
120-36 = 84 minutes left
So, if 120 is the 100% of the meeting, for 84 minutes:
120/100 = 84/x
1.2 =84/x
x = 84/1.2
x = 70%
70% of the meeting is left.
Since the triangle is an equilateral triangle we know all of it's sides must be the same length, with that in mind the angles that make up the triangle must be equal as well. Knowing that a triangle's three interior angles make up 180 degrees we know that the size of each angle must be one third of this (as each angle must be equal).
180/3 = 60
then we may split the triangle along it's altitude into two special right triangles
more specifically two 30-60-90 triangles.
this means that the side with 30 degrees will be some value "x" where the side for 60 degrees will be related as it is "x*sqrt(3)" and the hypotenuse (which would be the side of the triangle) would be proportionally "2x"
this would mean that the altitude is the side associated with the 60 degree angle as such we can solve for "x" using this.
12= x*sqrt(3)
12/sqrt(3)=x
4sqrt(3)=x (simplifying the radical we get "x" equals 4 square root 3)
now we may solve for the side length of the triangle which is "2x"
2*4sqrt(3) -> 8sqrt (3)
eight square root of three is the answer.
