Answer:
r = 19.0
s = 17.7
Explanation:
In the given right triangle ABC,
Measure of Hypotenuse (AC) = 26
m(∠CAB) = 43°
By applying sine rule in the given triangle,
sin(43)° =

sin(43)° =

s = 26[sin(43)°]
s = 17.73
s ≈ 17.7
Similarly, by applying cosine rule in the given triangle,
cos(43)° =

=

r = 26[cos(43)°]
r = 19.02
r ≈`19.0
