Answer:
Sin x = a / b.
Step-by-step explanation:
The opposite side =a and the adjacent side = 4 (because tan x = a/4.
Cos x = 4/b so the hypotenuse = b ( because Cos = adjacent /hypotenuse.
So sin x = opposite /hypotenuse = a / b.
Answer:
5x^2(2x-7)
Step-by-step explanation:
Hope this helps!
When you put the equation given in slope-intercept form it becomes y=3x+8
After graphing this you find that the point (4,4) is not part of the equation.
Answer:
c 17
Step-by-step explanation:
because if you subtract 2 from 8 you would get 6,
6 times 2 is 12
add 5 to 12 and you get 17
Answer:
18.4°
Step-by-step explanation:
Use law of cosine.
a² = b² + c² − 2bc cos A
11² = 20² + 28² − 2(20)(28) cos A
121 = 1184 − 1120 cos A
cos A = 0.949
A = 18.4°
