Answer:
measure of angle C = 18°
c = 2.47
a = 7.61
Step-by-step explanation:
Make sure your calculator is in degree mode.
Angle A measures 72°, so angle C measures 18° (Angles A and C are complementary angles, so their sum is 90°).
[tex] \sin(18) = \frac{c}{8} [/tex]
[tex]c = 8 \sin(18) = 2.47[/tex]
[tex]a = 8 \cos(18) = 7.61[/tex]
