Explanation:
Hello!!!
Given, VXW is a Right angled triangle where WV =4 and XV =5.
now, by taking reference angle as angle W, and using tangent we get;
p=5
b=4
again,
tan thita =p/b
tan thita = 5/4
so, tan thita =1.25.
now, to find angle W, we should do tan thita inverse;
or, (tan thita)-1= tan thita-1(1.25)
or, (tan thita) -1 =51.3401°.
Now, by rounding off we get,
tan thita (angle W )= 51°.
Hope it helps....
