If arctan 4/3 = the tangent of that angle will be 4/3 , opposite 4 over adjacent 3
Now, you only have to take the sin of that angle it's opposite 4 over hypotenuse 5.
You will get that the answer is 4/5
hope this helps
If 1 and 2 becomes multiplayed gave 3 and 3+3=4 (4-2)+(4-1)= 2+3=4 and 4 is n.
4X-8=12
+8 +8
4x/4=20/4
X=5
A 1:4
Find a common factor. In this case it’s 15
15/15=1 60/15=4
Therefore the answer Is 1:4
