Primcipal 739.30 Total = 778.90

Found by trial and error. I tried using equations but when you have TWO unknowns, it's (I think) impossible.

Rearrange the equation so uuu is the independent variable. -12u+13=8w-3

Sunny_sXe [5.5K]

Step-by-step explanation:

$- 12u + 13 = 8w - 3 \\ - 12u + 13 + 3 = 8w \\ - 12u + 16 = 8w \\ w = \frac{ - 12u + 16}{8} \\ w = \frac{ - 3}{2} u + 2$

I hope that is useful for you :)

In circle N, KL ≅ ML. What is the measure of ?

pentagon [3]

This is the concept of geometry, for us to get the value of JM we will requires to get the value of x first;
From the diagram we have been told that;
KL=ML
KL=7x+7
ML=8x-3
thus;
8x-3=7x+7
collecting the like terms we get;
8x-7x=7+3
x=10
But, JM=13x+2
substituting the value of x in JM we get:
JM=13(10)+2
JM=130+2
JM=132
The answer is 132°
