Using the image I gave you, you don't need to solve for x.
So tan is opposite/adjacent
sin: opposite/hypotenuse
cos: adjacent/hypotenuse
Take theta and do: adjacent/hypotenuse which is cosine
cos theta = adjacent/hypotenuse
cos theta = 1.5/9
inverse cos = 1.5/9 and the answer is: 80.4 degrees

2(x + 2) + 3z = 2(x + 1) +1
Oxana [17]

Answer:

Answer:x=

−3z−1

0

Step-by-step explanation:x=

Step 1: Add -2x to both sides.

2x+3z+4+−2x=2x+3+−2x

3z+4=3

Step 2: Add -3z to both sides.

3z+4+−3z=3+−3z

4=−3z+3

Step 3: Add -4 to both sides.

4+−4=−3z+3+−4

0=−3z−1

Step 4: Divide both sides by 0.

0

0

=

−3z−1

0

x=

−3z−1

Find the equation of this line.<br> y = x + [ ]
Art [367]

Answer:

y = x + 3

Step-by-step explanation:

The equation of a line is y=mx + b, where m is the slope and b is the y-intercept.

In this case, the slope of the line is 1, and the y-intercept (the point where the line crosses the vertical axis) is 3.  So you just need to plug in the 3 in place of b.

y = mx + b

m = 1

b = 3

y = x + 3

What is the solution to this equation? −1/4(x+1 2/3)=−2 1/5
pogonyaev

Answer:

x = 107/15

Step-by-step explanation:

Our first step should be to turn all of the mixed fractions into improper fractions. So, 1 2/3 becomes 5/3, and -2 1/5 becomes -11/5. We now get -1/4(x + 5/3) = -11/5. Now we should divide both sides by -1/4, and we get x + 5/3 = -11/5 x -4 = 44/5. So x + 5/3 = 44/5. We want the denominator to be equal on both sides so a common denominator could be 15. 5(5)/3(5) = 25/15. 44(3)/5(3) = 132/15. So now we have x + 25/15 = 132/15. We subtract both sides by 25/15 and we get x = 107/15.
