Answer:
n = 23
Step-by-step explanation:
if 1/2 (n-5) = 1/2 (23-5)
that must mean that n=23.
and if you are just looking for 1/2 of 23-5 that is just 9. (23-5) = 18 and half of 18 is 9
Answer:
820
Step-by-step explanation:
Hi so if your area is 4756, the base would be 820
Answer:
CotR = -√3
Step-by-step explanation:
In the 4th quadrant, sin is negative;
Since Cos R = √3/2,
Adjacent = √3
Hypotenuse = 2
Get the opposite;
opp^2 = 2^2 -(√3)^2
opp^2 = 4 - 3
opp^2 = 1
Opp = 1
Get sinR
Sin R = opp/hyp
SinR= -1/2
CotR = cosR/sinR
CostR = (√3/2)/(-1/2)
CotR = √3/2* -2/1
CotR = -√3
If n is 2, you substitute 2 for n and multiply 5(2)+8= 10 +8 = 18
<u>Given</u>
AC = BC
<u>Substitution</u>
∠1 = ∠3
<u>Base ∠'s of isosceles triangle =</u>
∠1 = ∠3
<u>Vertical angles =</u>
∠2 = ∠3
