Answer:

First notice that θ is in quadrant I, where the sine and tangent will also be positive.

Then draw the angle in quadrant I. Drop a perpendicular to the x axis.

Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.

Then sinθ=vertical/hypotenuse=  24/25 and tanθ= vertical/horizontal=  24/7

In the equation z/6 =
Nikitich [7]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Isolate the variable  using inverse operations."

»»————- ★ ————-««  

Here’s why:

To solve for a variable, we would have to isolate it on one side.

To isolate it, we would use inverse operations on both sides on the equation until the variable is isolated.

There are no like terms in the given equation.

⸻⸻⸻⸻

\boxed{\text{Solving for 'z'...}}\\\\\frac{z}{6} = 36\\-------------\\\rightarrow (\frac{z}{6})6 = (36)6\\\\\rightarrow  \boxed{z = 216}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Pleaseeeee anyone want to help me on this??? WILL MARK BRIANLIEST

Answer:

The Length of <em>JK</em> is 10

Step-by-step explanation:

Because <<em>J </em>is congruent to <<em>L</em> we know that the triangle in question must be isosceles as in an isosceles triangle two angles opposite of each other are equal. (This is also true for equilateral triangles, however, in an equilateral triangle all sides must be congruent, so we can rule equilateral out as <em>LJ </em>is not congruent to <em>KL.) </em>This means that the triangle must be isosceles.

In an isosceles triangle the side opposite each other are congruent, and the angles opposite each other are congruent when split down the line of symmetry.

Therefor, the length of <em>JK </em>must be congruent to the length of <em>KL. </em>In other words if <em>JK </em>= 10, then <em>KL </em>must equal 10 as well.

A line includes the points (0,2) and (1,6) What is the equation of the line in slope intercept form?
erica [24]

Answer:

y = 4x + 2

Step-by-step explanation:

\frac{y^{2}-y^{1}  }{x^{2} -x^{1} }

\frac{6-2}{1-0} = \frac{4}{1}

y = 4x + 2

How do i fill in this chart
yulyashka [42]
In the box where 'Tails' and 'Not six' is, write 68. Then right under that you ADD 50 and 68. Then under 'Six' and 'Tail' you MINUS 79 and 68. And finally under that one you ADD 21 and the answer you got. 

So in the end this is how it should look:
