Answer:
24°
Step-by-step explanation:
Oh, okay. So this is like (kinda?) the opposite of what I did in the last one. This time, instead of finding the side length of the imaginary triangle, you are trying to find the angle of elevation (that's what I call it)
sin θ = 200/500
θ = sin^-1 (200/500)
θ = 23.578...
Rounded:
θ = 24°
Answer:
x^8-x^6+x^3-5
Step-by-step explanation:
The top exponent goes before
16² = 18² + 19² - 2(18)(19)cos(z)
256 = 324 + 361 - (684)cos(z)
256 = 685 - (684)cos(z)
-429 = -684cos(z)
cos(z) = -429/-684
z = cos⁻¹ (0.627)
z = cos⁻¹ (cos 51) [ Cos 51 = 0.627 ]
z = 51
In short, Your Answer would be: 51
Hope this helps!
