<span>the formula that I used would be
p = a √( 2 - 2 cos(A) ) = a √( 2 + 2 cos(B) )q = a √( 2 + 2 cos(A) ) = a √( 2 - 2 cos(B) )<span>p2 + q2 = 4a2
this would give us these measurements for the diagonals
p=9
q=15</span></span>
Answer:
13 bags
Step-by-step explanation:
Area of the lawn: A=lw
w= 64 ft
P= 2(l+w)= 278 ft ⇒
bags of seed required:
- 4800/384= 12.5 so 13 full bags needed

Answer:</h2>
<h3>
<em>x=45degrees</em></h3>
<h2>
Step-by-step explanation:</h2>
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees
Ok so what's the question?
