Answer:
z^3 • z^3 ? or z^3^2 ?
Step-by-step explanation:
Answer: choice B
Angle A = 63 degrees
side a = 13.4
side b = 6.8
-----------------------------------------------
-----------------------------------------------
Given Info:
Angle C = 90 degrees
Angle B = 27 degrees
side c = 15
What is needed to be found:
Angle A, side a, side b
Finding side a
cos(angle) = adjacent/hypotenuse
cos(B) = BC/AB
cos(B) = a/15
cos(27) = a/15
15*cos(27) = a
13.3650978628256 = a
a = 13.3650978628256
a = 13.4
Finding side b
Using the pythagorean theorem
a^2 + b^2 = c^2
(13.3650978628256)^2 + b^2 = 15^2
178.625840882906 + b^2 = 225
178.625840882906 + b^2 - 178.625840882906 = 225 - 178.625840882906
b^2 = 46.374159117094
sqrt(b^2) = sqrt(46.374159117094)
b = 6.809857496093
b = 6.8
Finding angle A
sin(angle) = opposite/hypotenuse
sin(A) = BC/AB
sin(A) = a/c
sin(A) = 13.3650978628256/15
sin(A) = 0.89100652418838
arcsin(sin(A)) = arcsin(0.89100652418838)
A = 63.0000000000016
A = 63
Answer:
h = 80
Step-by-step explanation:
Remark
The general Volume formula for a pyramid is V = 1/3 * B * h
Givens
base edge = 3 m
V = 240 m^2
Solution
V = 1/3 * B * h
B = s^2
B = base edge^2
B = 3^2
B = 9
240 = 1/3 * 9 * h multiply by 3
240 * 3 = 9 h Divide by 9
80 = h

Given:
Substitute the given value into the formula and solve for r:
Answer:
9: 60
10: 28
11: 16
12: 44
Step-by-step explanation:
if 12 is right, I'm assuming the question is asking what the difference in percentage between the shows are.
