Determine which of the two acute angles has a cosine of 4/5.
1 answer:
Answer:
CosA = 4/5
Step-by-step explanation:
The acute angle with cosine of 4/5
Recall from trigonometry ;
Cosine = Adjacent / hypotenus
From the right angled triangle Given:
For angle A :
Opposite = BC = 8
Hypotenus = AC = 10
Cos A = BC / AC = 8 /10 = 4 /5
CosA = 4/5
For C :
Opposite = AB = 6
Hypotenus = AC = 10
Cos C = 6 /10 = 3 /5

Increase 25%
25%=1/4
1/4 of 1700=425
increase 25%
1700+425=2125
