Answer:
r= RE/I
Step-by-step explanation:
E=I(R+r)
divide both sides by I
E/I = R+r
subtract both sides by R
R(E/I) = r
r = RE/I
Answer:
Step-by-step explanation:
Best advice: make a sketch (which I can't do here).
When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).
Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
