Answer:
{120°, 420°, 480°, 780°, 840°}
Step-by-step explanation:
From your knowledge of the short table of trig functions, you know that ...
sin(60°) = (√3)/2
and that the sine of the supplement of this angle has the same value. Of course, the sine function is periodic with period 360°, so the solutions will all be of the form ...
θ = 90° ± 30° + k·360°
for any integer k.
For the range of interest, the angles are ...
90° +30° = 120°
360° +90° -30° = 420°
360° +90° +30° = 480°
2·360° +90° -30° = 780°
2·360° +90° +30° = 840°

Answer:
The square root of 49 is 7.
Step-by-step explanation:
To find the square root of 49, you would need to look at the possible multiplication equations. For example:
1 x 49 = 49
7 x 7 = 49
49 x 1 = 49
As you can see, 7 x 7 would have the square root of 49, which is 7.
7^2=49
.
In conclusion, the square root of 49 is 7
Answer:
0 and 2
Step-by-step explanation:
To find zeros set f(x)=0 and solve for x
now factor out x
set each factor =0 and solve for x
no solution for x
zeros of f are 0 and 2
