Answer:

A = 38°

Step-by-step explanation:

We are going to use cosine law to find angle A where

a = 4.7

b = 3.9 m

c = 2.9 m

{c}^{2}  =  {a}^{2}  +  {b}^{2}  - 2ab \cos(  \alpha )

or

\cos( \alpha  )  =  \frac{ {a}^{2}  +  {b}^{2} -  {c}^{2}  }{2ab}

cos A = [(4.7)^2 + (3.9)^2 - (2.9)^2]/2(4.7)(3.9)

= 28.89/36.66

= 0.788

A = arccos(0.788) = 38°
