What is the coefficient of b in the expression b + 10? explain.

The coefficient of b is 1

Step-by-step explanation:

we know that

In a mathematical equation, a coefficient is a constant by which a variable is multiplied

so

A coefficient is a constant multiplied by a variable.

In this problem we have

b+10

Rewrite'

b+10=(1)b+10

therefore

The coefficient of b is 1

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.
