Question

In ΔVWX, v = 21 cm, w = 64 cm and ∠X=23°. Find the length of x, to the nearest centimeter.

Answer 1

Answer:

its b just toook the test

Step-by-step explanation:

Answer 2

Answer:

45 (in centimeters)

Step-by-step explanation:

In ΔVWX we have to find the length of the third side.

When the length of two sides of a triangle and the included angle is given

we can find the length of third side by applying cosine law.

According to cosine law, in a ΔVWX

$x^{2} =v^{2}+w^{2} -2vwcosX$

                $=21^{2}+64^{2}-(2\times21\times64\times cos23)$

                =2062.683 $(cm)^{2}$

              $x=45$cm (approximating it to nearest integer)
