Answer:
cos ∠CBD = - 4√41 / 41
Step-by-step explanation:
AB = 4 ΔABC = (4 x AC) / 2 = 10
AC = 5
BC = √5² + 4² = √41
cos ∠CBD = cos (180° - ∠CBA) = cos 180° cos ∠CBA + sin 180° sin ∠CBA
(cos 180° = - 1 sin 180° = 0 cos ∠CBA = 4 / √41 )
cos ∠CBD = (-1) x cos ∠CBA = - 4 / √41 = - 4√41 / 41

Answer:
2
Step-by-step explanation:
Given
7x + 2 = 16
Subtracting 2 from both sides
7x + 2 - 2 = 16 - 2
7x = 14
Dividing both sides by 7
7x / 7 = 14 /7
x = 2
Hope it will help :)
