Answer:
x = 10 , 45 degrees.
Step-by-step explanation:
This seems a tricky one .
I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2
so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes
2 sin 3x cos 2x - cos 2x = 0
cos 2x ( 2 sin 3x - 1) = 0
so 2 sin 3x = 1
sin 3x = 1/2
giving 3x = 30 degrees and x = 10 degrees
or cos 2x = 0
so 2x = 90
giving x = 45 degrees.
Answer:
5+3 is Amy, so Amy is 8
Step-by-step explanation:
So, lets say amy is a
and gabriella is g
WE know that g=5, because gabriella is 5 years old
And, Gabriells is younger than Amy, so we need to add to get Amy's age
So, 5 ( Gabriella's age ) + 3=Amy
So, 5+3= Amy
So Amy is 8
