To find the value of the b angle.
First, label the sides of the right angle
The biggest side is always the hypotenuse
The side between the right angle and angle A is the adjacent side.
and the other side it's my opposite side.
Let's use the trigonometric function to find the value of b
I have the value of the hypotenuse
h = 7
and the value of my opposite side
opp = 3
So we need a trigonometric function that involves my hypotenuse and the opp
sin = opp/ hyp
Replace the values
sin b = 3/7
Solve the equation for b
b = arcsin (3/7)
b = 25.376
Rounded to hundredths
b = 25.37
