Solve for x.
A) 11
B) 9
C) 6
D) 7

Step-by-step explanation:

Angle  BCA is inscribed in that circle.  The rule is that the inscribed angle is half the measure of the arc it intercepts.  The arc it intercepts is arc AB which measures 96 degrees.  That means that

and

4x + 4 = 48 and

4x = 44 so

x = 11

Choice A is the one you want.

you should at least use a calculater

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.
