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

To determine the measurement of angle 4, we need more information about the geometric figure or diagram you are referring to. Angle measurements depend on the specific shape and context in which they are found. Please provide additional details or a description of the figure so that I can assist you in a step-by-step manner.

In order to find the measurement of angle 4, we need some additional information or the relationship between angle 4 and angle three. If you can provide more details about the given figure or any known relationships between these angles, I can help you determine the measurement of angle 4.

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?

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
