That expression is written like so:
(5 + d)/(12 - w)
18 = x

5 4
x = 18•4 / 5
72/5 = 14.4 final answer
Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
The answer is B (Sorry for the bad handwriting.)
