Answer:
Length is 22.5 ft
Width is 16.5 ft
Step-by-step explanation:
4L-w=73.5
4L=73.5+w
L=(73.5+w)/4
P=78
P=2L+2w
78=2[(73.5+w)/4]+2w
78=(73.5+w)/2+2w
78=(73.5+w+4w)/2
2•78=73.5+5w
156=73.5+5w
156-73.5=5w
82.5=5w
82.5/5=w
16.5=w
L=(73.5+w)/4
=(73.5+16.5)/4
=90/4
L=22.5
Step-by-step explanation:
2•4 =8
8/3 =2 2/3
answer : 3
Answer:
Step-by-step explanation:
if 
, then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.
The other leg (specifically the opposite one) will be equal to 
by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = 
.
cot(x) is defined as adjacent over opposite, which is equal to 
That means that the first option, the leftmost one, is correct.
Answer:
5
Step-by-step explanation:
okay, let's start with the -(-2). In math, the negative of a negative is positive. so basically, the -(-2) becomes a positive. The positive version of -2 is +2. So, the equation becomes 3+2, which is 5.
