Find the value of x.
a) x = 2
b) x = 3
c) x = 33
d) x = 52

B) x = 3

Step-by-step explanation:

The given triangle has three angles:

∠R, ∠S and ∠T

The exterior angle theorem says that

∠S+∠T = ∠R

Putting the values of angles

(57+x) + 25x = 45x

57 + x + 25x = 45x

57+26x = 45x

57 = 45x - 26x

57 = 19x

x = 57/19

x = 3

Hence, the correct answer is:

B) x = 3 ..

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
