Answer:
7 x 4
Step-by-step explanation:
Let the width be x, length will be 3x-5. ATQ, x(3x-5)=28. x=4 and x=-7/3, since length isn't negative, x=4. Width=4 and length=7
Answer:
12/7 or E
Step-by-step explanation:
Answer:
ok hold on ill figure it out for u
Step-by-step explanation:
it is 55
you do 2 x 12 x 8 = 192-3 cubed is 165 the 165/3 =55

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
3a+b+a+b = (3a+a) + (b+b) = 4a + 2b
