From the last time i did it, i believe its B
Answer:
y = 8
x = 9
Step-by-step explanation:
given equation,
x + y = 17 ........(1)
9 x - y = 73...........(2)
writing in matrix form
A X = B
using augamented matrix A|B
using row transformation
R₂ = R₂ - 9 R₁
now,
now
-10 y = -80
y = 8
and
x + y = 17
x = 17 -8
x =9
Quite easy!
Just follow SOH-CAH-TOA
Sine Opposite Hypotenuse; Cosine Adjacent Hypotenuse; Tangent Opposite Adjacent.
To find the measure of angle x, use tangent or opposite over adjacent.
So 26/53= 0.49
And using a tangent table, the closest to 0.49 is 26°

⟹Answer:
➧Lucas can cut the wire into 12 pieces.
Step-by-step explanation:
⟹<u>Lets Solve!</u>
⟹The first step is to convert into !
To do this we must find what number multiplied by 4 equals 16.
16 ÷ 4 = 4
⟹Now we know our multiplier is 4. So lets multiply the numerator and denominator by 4.
⟹Next we just divide by .
÷ = 12
➧Lucas can cut the wire into 12 pieces.
Woohoo! Brainliest appreciated! Hope I helped!
