Answer: x = 6

Step-by-step explanation:

The midsegment is half of the side it's parallel to.

Therefore 2*(3x-1) = 34

3x-1 = 17

3x = 18

x = 6

An image point after a 180 rotation is (3,7). What were the coordinates of the pre-image point?(A)Z(-3,-7) (B)Z(7,3) (C)Z(-7,-3)

Ilia_Sergeevich [38]

Answer:

(A)Z(-3,-7)

Explanation:

The rotation of a point (x,y) by 180 degrees gives the point (-x,-y).

That is:

$\text{Rotation by }180^0=(x,y)\rightarrow(-x,-y)$

If the image point after rotation is (3,7), the coordinates of the pre-image will be:

$(x,y)=Z(-3,-7)$

The correct option is A.

Answer: fifty four degrees (54)

Step-by-step explanation: Using the law of sines you'd multiply both sides by b then plug in the known values... sin(B)= 9/11xsin(80degrees). Then, you'd evaluate to find B and after solving you'd reach 54
