A wire is attached to the top of the tower and to a point on the ground that is 38 m from the base of the tower. If the wire makes a 68° angle with the ground, how tall is the tower?
Draw a sketch of a vertical right-angled-triangle with base angles being 90 & 68. The length of the base is 38. Define the height as 'h'.A wire is attached to the top of the tower and to a point on the ground that is 38 m from the base of the tower.

Hi jolliebollie,A wire is attached to the top of the tower and to a point on the ground that is 38 m from the base of the tower. If the wire makes a 68° angle with the ground, how tall is the tower?
So \(\displaystyleA wire is attached to the top of the tower and to a point on the ground that is 38 m from the base of the tower. If the wire makes a 68° angle with the ground, how tall is the tower?
No, Shiloh, that is wrong!So \(\displaystyle tan(68)= \frac{38}{h}\) where h is the height of the tower. Can you solve for h?
You get back in your corner and stop muddying the waters even further. ???... or \(\displaystyle \cot(68)\degree = 38/h\), if you insist on using 38/h
Is that how you approximate -0.49º ?\(\displaystyle \cot(68)\degree\)
