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

42.73568802
Step-by-step explanation:
6.973568802×10=69.73568802
69.73568802-27=42.73568802

Answer:
c = 75 in
Step-by-step explanation:
The hypotenuse of a right triangle is found by the Pythagorean theorem:
<em>a² + b² = c²</em> (a and b are the legs, c is the hypotenuse)
Plug in: <em>45² + 60² = c²</em>
Square + square root: √(2025 + 3600) = c
Add: √5625 = c
Square root: 75 in = c (no negatives because we are finding distance)
