Answer:
55°
Step-by-step explanation:
The following data were obtained from the diagram given above:
Adjacent = 4
Hypothenus = 7
Angle A =?
The value of angle A can be obtained as follow:
Cos A = Adjacent / Hypothenus
Cos A = 4/7
Take the inverse of Cos.
A = Cos¯¹(4/7)
A = 55.1° ≈ 55°
Therefore, the value of angle A is approximately 55°.
