Question

9. The difference of two complementary angles is 30°. Then, the angles are
(a) 60°, 30°
(b) 70°, 40°
(d) 20°, 50°
(d) 105°, 75°​

Answer 1

Answer:

option (a)

Step-by-step explanation:

option (a) is the correct answer because:

complementary angle means when we add two angles we must get 90°

therefore 60+30 = 90

and 60-30=30

therefore the answer is option (a) 60°,30°

Answer 2

Answer:

we know angle between two complementary line s is 180 as difference between line is 30° then two angles are 105° ,75° because 105°+75°=180° and difference is 105°-75°=30.
