Answer:
AB = 17 cm
Explanation:
NOTE: This is a mathematics question. Nevertheless, the answer to the question is given below
Please see attached photo for diagram.
The length of AB can be obtained as follow:
Angle A = 54°
Adjacent = 10 cm
Hypothenus = AB =?
Using the Cos ratio, we can simply obtain the length of AB as follow:
Cos A = Adjacent /
Cos 54 = 10 / AB
0.5879 = 10 /AB
Cross multiply
0.5879 × AB = 10
Divide both side by 0.5878
AB = 10 / 0.5878
AB = 17 cm
