Answer:
Step-by-step explanation:
I think the best way to do this is to find B using the cos law. The two other angles are equal
b = 3sqrt(3)
a = 3
c = 3
b^2 = a^2 + b^2 - 2ab*cos(B)
(3sqrt(3)^2 = 3^2 + 3^2 - 2*3*3 * cos(B)
27 = 9 + 9 - 18*cos(B)
27 = 18 - 18*cos(B)
9 = - 18*cos(B)
9/-18 = cos(B)
-1/2 = cos(B)
B = cos-1(-1/2)
B = 120
<A + <C + 120 = 180
<A = <C
2A + 120 = 180
2A = 60
A = 30
The question says angle A so that's what I did.
Answer:
(1, 1), (2, 4), (3, 9), (4, 16)
Step-by-step explanation:
You recognize that, of the numbers in Y, 20 is not a square. You also recognize that the remaining values of Y correspond to the squares of the values of X:
(x, x^2) = {(1, 1), (2, 4), (3, 9), (4, 16)}

Step-by-step explanation:
Hi ^-^
If your talking about the emergency hotline for police,ambulance, or fire you simply dial 9-1-1!
Hope this helps and please mark as brainliest
Step-by-step explanation:
A 1 / A 2 = B2 / B1
4 / A 2 = - 72 / 9
A 2 = - I / 2
