Answer:

x = 19

Step-by-step explanation:

The two angles form a right angle

A right angle has a measure of 90 degrees

Thus, x + 14 + 3x = 90

               ^This is the equation we will use to solve for x

x + 14 + 3x = 90

step 1 combine like terms

x + 3x = 4x

we now have 4x + 14 = 90

step 2 subtract 14 from each side

90 - 14 = 76

14 - 14 cancels out

we now have 76 = 4x

step 3 divide each side by 4

4x / 4 = x

76 / 4 = 19

we're left with x = 19

in a video game an object represented by the point is rotated counterclockwise 350 degrees about an origin. what are the new coo
agasfer [191]

If the point (3,2) is rotated counterclockwise 350 degrees about an origin, then the new coordinates if new point will be (3.28,1.44).

Given that the point is (3,2) and the point is rotated counterclockwise 350 degrees about an origin.

We are required to find the new coordinates.

Origin is a point where both the values of x and y are equal to zero.

a=arc tan (2/3)=33.7

r=\sqrt{3^{2} +2^{2} }

=\sqrt{13}

b=a+350

=33.7+350

=383.7 degrees

x=r cos b=\sqrt{13} cos 383.7=\sqrt{13}*0.91=3.28

y=r sin b=\sqrt{13} sin 383.7=\sqrt{13}80.40=1.44

Hence if the point (3,2) is rotated counterclockwise 350 degrees about an origin, then the new coordinates if new point will be (3.28,1.44).

Answer:

  about 1.4288993 radians

Step-by-step explanation:

The angle to terminal arm A is ...

  ∠A = arctan((-4/5)/(-3/5)) ≈ 4.0688879 radians

The angle to terminal arm B is ...

  ∠B = arctan((-1/√2)/(1/√2)) ≈ 5.4977871 radians

Then the angle between the arms is ...

  5.4977871 -4.0688879 ≈ 1.4288993 . . . radians
