Question

If angle three is 25° what is the measurement of angle 4

Answer 1

We know that when combining equations and an inequality, it is usually easier to start with the inequality and substitute in the equations. So let’s start with our inequality:

∠B>90°

We want to combine this inequality with our equation, so let’s solve our equation for ∠B:

∠B=180°–∠A–∠C

Substituting the right side of this equation for ∠B in our inequality we get:

180°–∠A–∠C>90°

We know that ∠A=25°, so let’s plug that in now:

180°–25°–∠C>90

Answer 2

No way to answer that question.

We don't know what relations "angle three" and "angle 4" have with each other . (why use words for 3, then digits for 4 ???)

Usually we see such naming when discussing parallel lines with
a transversal cutting them, but who can tell?
