We have been given that in ΔRST, s = 93 inches, ∠S=123° and ∠T=28°. We are asked to find the length of r to the nearest 10th of an inch.
We will use law of sines to solve for side r.
, where a, b and c are corresponding sides to angles A, B and C respectively.
Let us find measure of angle S using angle sum property of triangles.
Upon rounding to nearest tenth, we will get:
Therefore, the length of r is approximately 53.8 inches.
Oh come on haha, .25 , 3/8 , 0.53 , 65% , 87.5% , 4/4 in that order
You can show it a one of two was: b+4=c or c-4=b.
=4
In order to keep the equation right, both sides have to balance each other. When you only perform an operation ( I'm assuming you're talking about division or multiplication) on one side, it messes up the balance because now one side is larger than the other.
If you crossed multiplied than got an equation than x=6 ( if that's what your looking for)
