You write 100 as the denominator because 100 represents a whole whereas the numerator normally represents a percentage. Hope this helps!
10+5x=7x-4
1. simplify 7x - 5x
10=2x-4
2. add four to both sides
10+4=2x
+ 4 4
14=2x
3. divide 14 to both sides
14=2x
x=7
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
