6z -2 =0 so wouldnt you take 6 from 2 which would make z=4
ser-zykov [4K]
You would not subtract 2 from 6 because they are not like terms that you can combine - one of them contains a variable.

You would solve this equation like so:

6z - 2 = 0       The given equation
6z = 2            Add 2 to both sides
z = 1/3           Divide both sides by 6

Answer:
z = 1/3

Hope this helps.

Someone pls help, its on trig ratios.
Mars2501 [29]

Answer:

BC=12.8,\\AC=15.1

Step-by-step explanation:

In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.

Therefore, we have the following equation:

\tan 58^{\circ}=\frac{BC}{8}

Solving, we get:

BC=8\tan 58^{\circ}\approx \boxed{12.8}

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

\cos 58^{\circ}=\frac{8}{AC},\\AC=\frac{8}{\cos 58^{\circ}},\\AC\approx \boxed{15.1}

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.

Using the Pythagorean theorem to verify our answers:

8^2+(8\tan 58^{\circ})^2=\left(\frac{8}{\cos 58^{\circ}}\right)^2\:\checkmark

What is the range the 3rd side of the triangle can be be with 15 cm 14 cm ?
Volgvan

Answer:

20.5 cm

Step-by-step explanation:

I just used Pythagorean theorem  in which c^2=a^2+b^2

so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm
