Answer 1

Answer:

The answer to your question is:

Step-by-step explanation:

Data

B = 70°

c = 14

Process

                sin Ф = b / c

                b = c sinФ

                b = 14 sin 70

                b = 14 x 0.94

                b = 13.16

               cos Ф = a/c

               a = c x cos Ф

               a = 14 cos 70

               a = 14 x 0.34

               a = 4.76

 C = 90° it is a right angle

A = 180 - 90 - 70

A = 180 - 160

A = 20°
