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
3/8 * 6/7
6*3=18
8*7=56
18/56 simplified is 9/28

Answer:</h2>
<u><em> 17 + z -(-9)</em></u>
<u><em>+17 +17</em></u>
<u><em>(34) + (26)</em></u>
<u><em> z=60</em></u>
<h2>
Step-by-step explanation:</h2>
<em><u>You need to solve for Z so we need to get z by itself so take 17 and add it to both sides because whatever is on the left side of the equal sign is always what you need to add 17+ 17 then 17+(-9) you get your answers then add those two up then you get z=60.</u></em>
