Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
Applying Pythagoras Theorem in the right triangle ODB find the radius of the circle
A = 180 - 143 = 37
b = 143
c = a = 37
e = a = 37
f = 90 - 37 = 53
d = 180 - 85 - 37 = 58
g = 48
h = 180 -48 -48 = 84
k = 180 -84 = 96
m = 180 - 58 - 96 = 26
p = 180 - 26 - 85 = 69
r = 180 -69 = 111
s = p = 69

Answer:
2
Step-by-step explanation:
The solutions are ...
p +m|x +n| = k . . . . . given
m|x +n| = k -p . . . . . . subtract p
|x +n| = (k -p)/m = (p -k)/-m . . . . . . must have (p-k)/-m ≥ 0
x = -n ± (p -k)/-m
For the given conditions, m < 0, p > k, we are guaranteed that (p-k)/-m > 0, so there are 2 solutions.
Answer:
(2z)^3 or 8z^3
Step-by-step explanation:
"double z:" 2z
"raise the result (2z) to the third power:" (2z)^3 or 8z^3
Number * 4/5 * reciprocal of 2/5
number * 4/5 * 5/2 = number * 20/10 = number * 2
