Answer:

x=8 and QNR= 63°

Explanation:

90+8x-1+27=180

116+8x=180

8x=64

x=8

Answer:

8, m<QNR=63 degrees

Explanation:

So, lets go over what we know:

The angle that makes up (8x-1) and 27 degrees is a right angle.

A right angle is 90 degrees.

So, to solve for angle m<QNR and for x, we must subtract and solve using 27 degrees, and (8x-1).

Lets put this into equation form:

(8x-1)+27=90

Lets subtract 27 from both sides to get the (8x-1) alone:

(8x-1)=63.

So lets stop here real quick.

We need to find angle M<QNR. This is (8x-1)

So looking at what we have solved so far, angle M<QNR must be 63 degrees.

Now, lets solve further to find out what x is:

(8x-1)=63

Lets add x to both sides to get 8x alone:

(8x)=64

We dont need the parethese, for they do not have a function, so:

8x=64

Finally, lets divide 8 from both sides so we can make 8x into just x:

x=8

So x is equal to 8.

Overall:

x = 8

Angle m<QNR = 63

Hope this helps! :)
