what have you tried?
hard bough
what have you tried?
Tried to do perpendiculars to CA¹ and HA¹
Cause if they are equal it means that A¹B¹ is a bisector
Which means that CA¹B¹ is 45 degrees

imagine making 🔺️AA¹B to 🔺️B¹A¹B, then
<B¹A¹H = 3x, and x = 15°, so 3x = 45°, hence
<B¹A¹C = 90° - 45° = 45°

imagine making 🔺️AA¹B to 🔺️B¹A¹B, then
<B¹A¹H = 3x, and x = 15°, so 3x = 45°,...
How does <AA¹B equal 3x when x is 15°?
Cause <AA¹B is 90°

How does <AA¹B equal 3x when x is 15°?
oh sry I mean B¹A¹H

oh sry I mean B¹A¹H
Okay and why is B¹A¹H 45°?
