Question

If one angle equals 130 in a triangle and the other equals 96 then what does the angle labelled X equal

Answer 1

x = 46

Explanation:

This is basic trigonometry, so we can apply this procedure...

- The total sum of all angles in a triangle is 180 (no angle should be more than 180, this is the limit) and we only need to know just one angle labeled as x, this is represented as:

130 + 96 + x = 180

x = 130 + 96 - 180

- Now we just need to obtain x:

x = 130 + 96 - 180

x = 226 - 180

x = 46
