Given that <span>cos a = 3/5 and it is in the first quadrant :
then:
a=arccos 3/5
but
cot </span>θ=1/tan θ
thus to evaluate our vale we shall obtain the value for height since
adjacent=3
hypotenuse=5
thus
using Pythagorean theorem:
c²=a²+b²
hence
5²=3²+b²
b²=25-9=16
b=4
thus
tan θ=opposite/adjacent
tan a=4/3
thus
cot a=1/(4/3)=3/4
Answer:
(A) 11.5 ounces
Step-by-step explanation:
Multiply 3.25 by 4
3.25 x 4 = 13
Subtract 13 from 24.5
24.5 - 13 = 11.5
= 11.5 ounces
Your answer should be 264.
