?
When labelling a triangle you must:
use capital letters for sides and lower case letters for angles
1 of 5
Area of a Triangle is:
1/2 ab sin c
2 of 5
(sine rule) find the length of AB when angle CAB is 83∘, angle ACB is 53∘ and the size of the side AC is 7m (round to 3sf)
8.05m
3 of 5
for trigonometry the inverse of tan is used when
tan is brought to the other side of the equation
4 of 5
(cosine rule) find angle CAB when side AB is 8m, side BC is 10m and side CA is 7m (1dp)
