Question

Alpha + beta = 90 degree and alpha : beta = 2 : 1 then what then find sin alpha : sin beta

Answer 1

Answer:

sin a= root 3/2

sin b= 1/2

Step-by-step explanation:

a + b = 90

a:b = 2:1

Therefore,

2/3 * 90 = 60

&

1/3 *90 = 30

So, a= 60 and b=30

sin60= root3/2(exact trig values)

sin30= 1/2(exact trig values)
