Question

Two angles have a sum of 180 and are in the ratio 3:2 what is the size of the large angle HELPPP

Answer 1

108°

Explanation:

The angle ratio is given as ...

(large angle) : (small angle) = 3 : 2

Then the ratio of the large angle to 180° is ...

(large angle) : (sum of angles) = 3 : (3+2) = 3:5

The size of the large angle is ...

3/5 × 180° = 108°
