Question

Given SinB=.91 find the angle B in radians

Answer 1

Hello!

As you can see, the opposite side of this angle divided by the hypotenuse is 0.91. To find B, we could multiply by the arcsine using a scientific calculator.

sin$^{-1}$(0.91)≈65.5

Now, we need to convert this into radians. To do so, we multiply by pi divided by 180.

$\frac{\pi}{180} (65.5)$≈1.14

Therefore, angle B will form an arc of about 1.14 radians.

I hope this helps!
