Answer:
-13
Step-by-step explanation:
Plug in 10 as x into the function:
f(x) = -2x + 7
f(10) = -2(10) + 7
f(10) = -20 + 7
f(10) = -13
So, f(10) = -13
Answer:
(√1 - a²)
Step-by-step explanation:
cos(sin⁻¹ a) = cos x°
sin x° = sin (sin⁻¹ a) = a
as shown in the attached picture
sin x° = a/1 cos x° = (√1 - a²) / 1 = (√1 - a²)
Answer:
Sum is equal to 90 degrees
Answer:
the degree of x can be added to 120 to get 180. they form a straight line which is 180°. subtract 120 from 180 to get you answer.
180-120=60 so x=60
