S = 10x^2
S/10 = x^2
+or-sqrt(S/10) = x
+or- sqrt(S10)/10 = x
so
_inverse = +or-sqrt(10x)/10
Answer:
Step-by-step explanation:
36/78 = 0.46153,,,, nope.. not a choice
36/123 = 0.2926.... so the last answer looks good
Answer:
A
Step-by-step explanation:
Since the two labelled angles are corresponding angles, they are equal.
10x = 9x + 10
Subtract both sides by 9x
x = 10
Also, if you need to know, the angle length is 100 degrees.
Have an awesome day! :)
