Question

Q7) a) The measures of two supplementary angles are in the ratio of 2:3. What are the measurements of the two angles? b) Find an angle which is two-thirds of its complement​

Answer 1

Answer:

supplementary angle = 180

so 2:3=

2/5×180= 36×2. { adding both the ratio , then we get 5}

=72

3/5×180=36×3

=108

therefore the measurement of the two angle = 72,108
