Answer:
X = 3
Step-by-step explanation:
3x + 4x - 12 = - 10x + 30 + 9
7x - 12 = - 10x + 39
7x + 10x = 12 + 39
17x = 51
x = 3
Answer:
is the name of your account from little mermaid? :DDD
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now just refer to the above ( also copy and paste the above on your computer some where so you have it always)
sin( D )= 28 / 53
sin( E ) = 45 / 53
cos(D) = 45 / 53
cos(E) = 28 / 53
Answer : HF ≈ 23.2 ft
Explanation :
Using the sine ratio in the right triangle.
sin75° = = =
Multiply both sides by 24
24 × sin75° = HF , thus
HF ≈ 23.2 ft ( to the nearest tenth )
