Answer:

x = 84°

Step-by-step explanation:

180 - 143 = 37

37 + 59 = 96

180 - 96 = 84°

Answer:

x = 84 degrees

Step-by-step explanation:

To solve this, we need to keep the following 2 things in mind:

a. A straight line will have an angle of 180 degrees.

b. A triangle's inside angles will have a sum of 180 degrees.

Knowing the first fact, we know that the unnamed angle to the left in the triangle PLUS the 143 degree angle, will equal 180.

143 + v = 180

I'm calling that angle v here.

Subtracting 143 from both sides:

v = 180 - 143 = 37

That angle is 37 degrees.

Now, our 2nd fact says that all inside angles in a triangle will add to 180.

Angle 1 = 59 degrees (bottom right)

Angle 2 = 37 degrees (bottom left)

Angle 3 = x (top)

59 + 37 + x = 180

96 + x = 180

Subtracting 96 from both sides:

x = 84

Answer:

x = 84 degrees

ollegr [7]

Answer:

x = 26.45

Step-by-step explanation:

Cos theta = adjacent side / hypotenuse

cos 50 = 17 /x

Switch the x and the cos 50

x = 17 / cos 50

x =26.44730506

Rounding to 2 decimal places

x = 26.45

Factorise fully x^3-x
MA_775_DIABLO [31]

Answer:

x(x+1)(x-1)

Step-by-step explanation:

We see that the two terms share an x, so we can pull that out:

x^3-x=x(x^2-1)

Now notice that we have a difference of squares (x^2-1). Given a difference of squares, a^2-b^2, this can always be factored into (a+b)(a-b). We can use this in this case: x^2-1=(x+1)(x-1).

So, our final factorized form is: x(x+1)(x-1).

Hope this helps!

Find the distance between (-2, 8) and (11, 2). Round to the nearest hundredth.
MakcuM [25]

Answer:

14.32

Step-by-step explanation:

We can find the distance using the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We then substitute (-2,8) as (x_1,y_1) and (11,2) as (x_2,y_2).

d=\sqrt{(11--2)^2+(2-8)^2} \\d=\sqrt{(13)^2+(-6)^2} \\d=\sqrt{169+36}\\d=\sqrt{205}=14.32
