Answer:

Step-by-step explanation:

1) 5 - [-5] = 5 + 5 = 10

2)8 - 13 = 8 + (-13) = -5

3) 12 +(-3) = 9

4) x + (-7) = 5

x - 7 = 5

x = 5 + 7

x = 12

We need to add 12 to (-7) to get 5

5) 7 - x = -5

7 = -5 +x

7 + 5 = x

12 = x

We need to take away 12 to 7 to get (-5)

6) 7 - (-10) = 7 + 10 = 17

Anyone know this?? it’s finding the sine of a triangle!!

LenKa [72]

Answer:

I'm not sure what you want me to answer from this, so I solved for every variable:

Angle A: 83°

Side b: 6.29

Side c: 5.8

Step-by-step explanation:

-----Angle A:

Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:

$A+51+46=180\\A+97=180\\A=83$

-----Side b:

Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:

$\frac{a}{sin(A)} =\frac{b}{sin(B)} \\\frac{8}{sin(83)} =\frac{b}{sin(51)} \\8.06=\frac{b}{0.78} \\6.29=b$

-----Side c:

$\frac{a}{sin(A)} =\frac{c}{sin(C)} \\\frac{8}{sin(83)}=\frac{c}{sin(46)} \\8.06=\frac{c}{0.72} \\5.8=c$

What is the difference of the two polynomials? (7y2 6xy) â€"" (â€""2xy 3) 7y2 4xy â€"" 3 7y2 8xy â€"" 3 7y2 4xy 3 7y2 8xy 3.

svet-max [94.6K]

The difference between the polynomials is 7y² + 8xy - 3

Polynomials are functions that have a degree of <u>power greater than two.</u>

<u />

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)

f(x, y) = (7y^2 + 6xy) - (-2xy + 3)

f(x, y) = 7y² + 6xy + 2xy - 3

f(x, y) = 7y² + 8xy - 3

Hence the difference between the polynomials is 7y² + 8xy - 3
