Question

Can you help me find the given angle?

Answer 1

tan 48/50
tan-1(48/50)=43.83

Answer 2

43.8°

Explanation:

Note, tan^-1 is the same as cot and they both are the same 1/tan

Using TOA..

`t * (o)/(a)`

Where t = tan, o = opposite (perpendicular) and a = adjacent (base)

Opposite = the magnitude opposite the angle

adjacent = line segment between angle and perpendicular line segment

o = 48° and a = 50°

Solve...

.. Let the unknown angle be B (beta)

• cotB = (48/50)
• Enter values in your calculator

== ~ 43.8° [usually we round to one decimal place or 1dp]
