Please help me and give me the explanation please: In Pitcher´s ERA, the earned run average, A is measured by the formula A = 9R/I, where R = runs allowed and I = number of innings pitched. Solve for the formula for I

I = 9R/A

Step-by-step explanation:

A = 9R/I

Multiply both sides by I.

AI = 9R

Divide both sides by A.

I = 9R/A

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
