AB = 14mm
BC = 29mm
B = 90°
Has to be done using trigonometric functions

Answer 1

What formula do I use?

Answer 2

Taking BC as the perpendicular and AB as the base;
\[\tan \theta =\frac{ perpedicular }{ base }\]

\[\tan \theta= \frac{ 29 }{ 14 }\]

Answer 3

I got 64.23 degrees (2dp) as my final answer.

Answer 4

Yep. Correct.
