If r=10 and s=31 find R. Round to the nearest tenth
Vsevolod [243]

Answer: option c.

Step-by-step explanation:

You need to remember the identity:

tan\alpha=\frac{opposite}{adjacent}

The inverse of the tangent function is arctangent. You need to use this to calculate the angle "R":

 \alpha =arctan(\frac{opposite}{adjacent})

You know that you need to find the measure of "R" and r=10 (which is the opposite side) and s=31 (which is the adjacent side), you can sustitute values into \alpha =arctan(\frac{opposite}{adjacent})

Then, you get:

R=arctan(\frac{10}{31})\\\\R=17.9\°

$9.54 divided by 18 balls = $0.53 per golf ball

Solve for the variable p Write the equation 4l +26p= 210. Write the equation in the form p = an expression.
Fittoniya [83]

Answer:

p = (105-2l)/13

Step-by-step explanation:

4l + 26p = 210

Isolate 26p by subtracting 4l from both sides

26p = 210-4l now divide by 26

p = (210-4l)/26 you can simply

p = (105-2l)/13
