Could someone please help me? If you know all the answers please write down what the answers are. Also, tell me how you got the answer. Will mark brainlist for the best answer for solving the equations or questions.

1. its B

2. you use pemdas

3. you use the second step of pemdas

Step-by-step explanation:

1. because all of the parts are equal and there are only four equal parts.

2. Pemdas=Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

3. Pemdas=Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

goog may have it for you

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.
