Answer:
4.5
Step-by-step explanation:
Do 3x3 as a whole square, do 9 divided by 2 which is 4.5
Answer:
A. x = 13
y = (13√3)/3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = (26√3)/3
Adjacent = x
Opposite = y
✔️Apply CAH to find x:
Cos 30 = Adj/Hyp
Cos 30 = x/(26√3)/3
√3/2 = x*3/(26√3) (cos 30 = √3/2)
√3/2 = 3x/(26√3)
Cross multiply
2*3x = (26√3)*(√3)
6x = 26*3
6x = 78
x = 78/6
x = 13
✔️Apply SOH to find y:
Sin 30 = Opp/Hyp
Sin 30 = y/(26√3)/3
Sin 30 = y*3/(26√3)
½ = 3y/(26√3) (sin 30 = ½)
Cross multiply
2*3y = (26√3)*1
6y = 26√3
Divide both sides by 6
y = (26√3)/6
y = (13√3)/3
Answer:
The correct options are,
x = -2 and x = 3
Step-by-step explanation:
It is given that,
x² - x - 6 = 0
<u>To find the solution of given equation</u>
x² - x - 6 = 0 can be written as
x² + 2x - 3x - 6 = 0
x(x + 2) - 3( x + 2) = =
(x + 2)(x - 3) = 0
Either (x + 2) = 0 or (x - 3) = 0
If (x + 2) = 0 then x = -2
If (x - 3) = 0 then x = 3
Therefore the correct options are,
x = -2 and x = 3
Interior alternate angles
