how do I solve an angle in right triangles. what is angle B?AB=7BC=3

Sagot :

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
