x = 45

135°

Step-by-step explanation:

180 - 45 = 135

3x = 135

3x/3 = 135/3

x = 45

45 degrees

Step-by-step explanation:

Since 45 and 3x are on a straight line together, they add up to 180 degrees. This means you can have the equation

45 + 3x = 180

subtract 45 from both sides

3x = 135

x = 45 degrees

step-by-step explanation:

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.
