Two complementary angle are in the ratio of 2:3 . find the angles

Two complementary angles are in the ratio of 2:3, find the measure of the complementary angle. 2+3=5 90/5=18.

72° &108°

Step-by-step explanation:

180°=2:3

2+3=5

2/5×180°=72°

3/5×180°=108°

answer: there are 453.592 grams in a pound.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
