Answer:
GH = 7
Step-by-step explanation:
The question is lacking a diagram. check the diagram in the attachment.
Given the right angled triangle as shown in the attachment.
Since one of the acute angle ∠ G = 45°, the other acute angle ∠I = 45 °. Using the trigonometry ratio to get the side GH. Taking GH as the adjacent and HI as the opposite side. According to TOA;
tan∠G = opp/adj
tan∠G = HI/GH
tan45° = 7/GH
GH = 7/tan45°
GH = 7/1
GH = 7
