Given SinB=.91 find the angle B in radians
labwork [276]

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!

Im trying to solve this but don’t understand how m-3(-5x+2)+x=42
timofeeve [1]
-3(-5x+2)+x=42
Distribute the -3 to the -5 and 2 so you would be left with
15x-6+x=42
Then you combine like terms and the x’s
16x-6=42
Add the 6 to the 42
16x=48
Then divide by 16 on both sides
X=3

I hope that helped.

What is the unit rate?<br> Will give brainliest
givi [52]
“Unit rate” is a comparison of any two separate but related measurements when the second of these measurements is reduced to a value of one. Calculating the unit rate in any set of circumstances will require the use of division.
