Answer:
Explanation:
Sum of all the angles is 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 40
Use cos x = adjacent side/hypotonuse
Use 50 as your reference angle
cos 50 = 19/c >cross multiply
c cos 50 = 19 >divide both sides by cos 50 to solve for c
c= 19/cos 50 >plug in
c=29.6
Now use tan x = opposite side/ adjacent side
Use 50 as your reference angle
tan 50 = b/19 >multiply both sides by 19
b= 19 tan 50 >plug in
b= 22.6
