Something along the lines of multiplying and adding
Answer:
x=12
y=
Step-by-step explanation:
Hey There!
to solve this problem we need to use the 30 - 60 - 90 triangle rule
So you are correct on x because the hypotenuse is 2x
24/2=12
y would equal 
as you could see in the image down below
Sin a * cos b + cos a * sin b=sin (a+b)
sin 78 * cos 42 + cos 78* sin 42=sin (78+42)=sin 120=sin(180-120)=
sin 60=√3 / 2
Answer: sin 78 * cos 42 + cos 78* sin 42=<span>√3 / 2</span>
Answer:
C
Step-by-step explanation:
Answer: 150
Step-by-step explanation:
20 is 1/3 of 60. So you can just multiply 50x3 so the answer becomes 150.
