Question

what is it?

Explanation:

Step1: Use the property of congruent right - angled triangles

Since the two right - angled triangles have two equal angles (44°) and a common side, they are congruent.

Step2: Apply the property of congruent triangles for side lengths

Corresponding sides of congruent triangles are equal. So, \(IF = IG\).

Step3: Determine the value of \(IF\)

Given \(IG = 89\), then \(IF=89\).

Answer:

89
