Calculate the size of angle CAG.

m(∠CAG) = 35°

Step-by-step explanation:

From the figure attached,

Apply Pythagoras theorem in ΔCAG,

Length of AC =

                      =

                      =

                      = 45

Now find the tangent of the given angle CAG,

tan(∠CAG) =

                  =

m(∠CAG) =

                =

                = 34.992°

                 ≈ 35°

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
