Answer:
Hi there!
Your answer is:
x= 18
Step-by-step explanation:
3x+70=8x-20
Isolate x on left side
3x+70=8x-20
-8x -8x
-5x +70 = -20
Isolate whole numbers on right side
-5x +70 = -20
-70 -70
-5x = -90
Isolate x by dividing both sides by -5
-5x = -90
/-5
x= 18
we know that
The measurement of <u>the external angle</u> is the semi-difference of the arcs which includes
so
m∠LMN=
therefore
the answer is 
Answer: -2(1/2)
Step-by-step explanation:

anyways...
calculate the difference first.
(-13/12) - 14/9
then, rewrite the expression.
-13/12 - 14/9
the solution is -95/36.
when it's converted to decimal form, it turns into -2.638. so, our BEST estimate for the value of the expression is -2(1/2) (the second option)
