Question

In , is a right angle. Find the remaining sides and angles. Round your answers to the nearest tenth.
a = 3, c = 19
a. = 9.1°, = 80.9°, b = 18.8
c. = 14.5°, = 75.5°, b = 18.8
b. = 80.9°, = 9.1°, b = 18.8
d. = 75.5°, = 14.5°, b = 18.8

Answer 2

Pythagorean theorem. c^2 -a^2=b^2

Answer 3

\[19^2-3^2=c^2\]

Answer 4

361-9=352

Answer 5

\[352=c^2\]

Answer 6

\[\sqrt{352}\]=c

Answer 7

c=18.76166304

Answer 8

However, this is not in the correct form. it gives you 18.8=c
