Divide I from both sides then subtract r from both sides, too so in the end:

R= (E-r)/I

E÷I =R+r

R=(E÷I) - r

Solve for x. round to the nearest hundredth if necessary.

Answer: $x=11.47$

Step-by-step explanation:

Given the angle of 55 degrees, you know that the adjacent side is "x" and the length of the hypotenuse is 20.

Therefore, you need to remember the following identity:

$cos\alpha=\frac{adjacent}{hypotenuse}$

Then, knowing that:

$\alpha=55\°\\adjacent=x\\hypotenuse=20$

You need to substitute these values into $cos\alpha=\frac{adjacent}{hypotenuse}$ :

$cos(55\°)=\frac{x}{20}$

Now, you can solve for "x":

$20*cos(55\°)=x\\x=11.471$

Rounded to the nearest hundreth:

$x=11.47$

How to find slope and y intercept from the equation ax+by=c?

melisa1 [442]

solve for "y" so it is in the form y = mx + b. "m" is the slope and "b" is the y-intercept.

ax + by = c

by = -ax + c <em>subtracted "ax" from both sides</em>

y = (-a/b)x + c/b <em>divided both sides by "b"</em>

Answer: slope is -a/b and y-intercept is c/b
