Find the value of the length x rounded to 1 DP.

ivanzaharov [21]

Answer:

x = 13.6 cm

Step-by-step explanation:

part A:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(39) = \frac{6}{adjacent}$

$adjacent = \frac{6}{tan(39)}$

$adjacent = 7.41$

part B:

using tan rule:

$tan(x) = \frac{opposite}{adjacent}$

$tan(44) = \frac{6}{adjacent}$

$adjacent = 6.213$

Total length of x:

part A + part B

$7.41 + 6.213$

$13.6$ cm
