Pls help no wrong answers pls

45°

Step-by-step explanation:

Sum of angles lying on any part(upper or lower) of a line is 180°.

=> (2x + 45°) + x = 180°

=> 3x = 180° - 45°

=> 3x = 135°

=> x = 135°/3

=> x = 45°

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
