Answer:
Step-by-step explanation:
Sine uses the ratio, so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.
You can't reduce this any further because there is an unknown variable.
Answer:
The original length of each side of the equilateral triangle = x =15 inches
Step-by-step explanation:
Let Original length of side of equilateral triangle = x
If it is increased by 5 inches, the length will become = x+5
Since in equilateral triangle all the ides have same length so,
New Length of side 1 = x+5
New of side 2 = x+5
New Length of side 3 = x+5
Perimeter of triangle = 60 inches
We need to find the value of x
The formula used is:
Putting values in formula and finding x
So, the original length of each side of the equilateral triangle = x =15 inches
