Answer:

x = 12

Step-by-step explanation:

Pythagoras' Theorem

$a^{2} = b^{2} + c^{2}$

a = 13

b = 5

c = x

$13^{2} = 5^{2} + x^{2}\\169 = 25 + x^{2}\\169 - 25 = x^{2}\\144 = x^{2}\\12 = x$

If A = 30° and r = 12, find x. (Round your answer to the nearest whole number.)

Margaret [11]

Answer:

$\boxed{12}$

Step-by-step explanation:

A = 30° and r = 12

$\sin A = \frac{r}{r + x}$

$\sin 30 = \frac{12}{12 + x}$

$\frac{1}{2} = \frac{12}{12 + x}$

$1(12 + x) = 2(12)$

$12 + x = 24$

$x = 24 - 12$

$x = 12$

Happy to help :)
