Answer:

x = 1

y = -2

Step-by-step explanation:

adding both quation we get

3x -2y + x + 2y =7 + -3

4x = 4

x = 1

substituting this equation in the earlier equation we get

3 * 1 -2y = 7

3 - 2y = 7

-2y = 4

y = -2

Answer:

x=1
y= -2

Step-by-step explanation:

3x-2y =7
x+2y= -3
4x=4
x=4/4
x=1
3x-2y=7
3(1)-2y=7
3-2y=7
-2y=7-3
-2y=4
2y=-4
y=-4/2
y= -2
Verify solution
x+2y= -3
1+2y= -3
2y=-3-1
2y= -4
y= -4/2
y= -2

Answer:

Law of Sines

Step-by-step explanation:

Law of Sines: $\frac{A}{sina} =\frac{B}{sinb} =\frac{C}{sinc}$

Step 1: Solve for m∠B

$\frac{25}{sin36} =\frac{27}{sinx}$

25sinx = 27sin36°

sinx = 27sin36°/25

$x = sin^{-1}(\frac{27sin36}{25} )$

m∠B ≈ 39.4°

Step 3: Find m∠C

180 - (36 + 39.4)

180 - 75.4

m∠C = 104.6°

What is angle F to the nearest degree?

nekit [7.7K]

Answer:

So we already knew all three sides, there are more than one way to do it, for example:

sin∠F = HG/HF = 12/13

cos∠F = GF/HF = 5/13

tan∠F = HG/GF = 12/5

ctg∠F = GF/HG = 5/12

All of them will give you the result which is approximately 67°.
