Find the measure of angle 4

m∠4 = 56°

Step-by-step explanation:

In this question we will find the relation between angle 4 and angle 1 first.

∠1 ≅ ∠2 [Vertically opposite angles]

∠2 ≅ ∠4 [Corresponding angles]

Therefore, ∠1 ≅ ∠4 [Alternate exterior angles]

Since, m∠1 = 56°

m∠4 = 56° will be the answer.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
