I need help with this one plz! (marking BRAINLIST) :) ​
miskamm [114]

Answer: (a) = 110 degrees, (b) = 8

If I understand the picture correctly, (a) wants you to find the angle K. It first shows us that both J to K, and L to K are equal in length of 11, thus there is no deviation in angle 35 degrees with L (so they both equal each other). Therefore, the angle K will equal 180 degrees subtracted by the sum of J and L, which is 110 degrees.

For (b), it appears that all the angles have the same singular mark at the edges, so all sides will equal 8.

I hope this helped!

If w/x=3, what does x/w equal
ruslelena [56]

Answer:

The value of x/w is 1/3.

Step-by-step explanation:

Consider the provided expression w/x=3

We need to find the value of x/w.

\frac{w}{x}=3

Now multiply both the sides by x.

\frac{w}{x}\times x=3x

w=3x

Now divide both the sides by w.

\frac{w}{w}=\frac{3x}{w}

1=\frac{3x}{w}

Divide both the sides by 3.

\frac{1}{3}=\frac{3x}{w}\times \frac{1}{3}

\frac{1}{3}=\frac{x}{w}

Hence, the value of x/w is 1/3.
