Answer:
see explanation
Step-by-step explanation:
(a)
(the side required )² = sum of squares of other 2 sides - ( 2 × product of other 2 sides and cos(angle opposite side required ) )
x² = 12² + 15² - (2 × 12 × 15 × cos71°)
(b)
x² = 144 + 225 - 360cos71°
= 369 - 360cos71° ( take square root of both sides )
x = ![\sqrt{369-360cos71}](https://tex.z-dn.net/?f=%5Csqrt%7B369-360cos71%7D)
≈ 16 cm ( to the nearest integer )
