Find your vague description solve the missing lengths and
ok so in this problem..
i am told to solve for all sides and angles in the right triangle
so the bottom side of the triangle is 6.2 in length
and all the other sides are unknown
in angles the the triangle is a right triangle and that angle is located on the left bottom side of the triangle, on the lower right angle the angle is 25 degrees
what are the missing sides and lengths?
Yes,
but the important thing is for you to be able to think it through...
We want to find out what b is, using and 6.2.
We need b on one side and the other two combined correctly to calculate b.
There are lots of ways to combine two numbers..add, subtract, multiply, divide, etc.
but there is only one way to combine those numbers to get b.
b being in the denominator position is inconvenient,
so first multiply both sides by b.
That gets b "above the line.
However, it's now multiplied by ,
therefore if we divide both sides by , we are left with b all alone on the left,
which is what we wanted...
The important thing is to understand why you take the steps,
not just "do this", then "do that"...
Or understand the way shown earlier by inverting the fractions.
It all depends on where the side you are looking for is in the fraction,
so you may have to do a slightly different calculation,
but the idea is to get the side you want "by itself".
In this case....
This time we can get "a" by itself in one step by multiplying both sides by 6.2
So it's faster!
Finding "b" takes a little longer, because we begin with it under the line.
