Answer:

∠y = 62.5°

∠x = 27.5°

Step-by-step explanation:

z is right angle. ∠z = 90°

∠x = ∠y - 35

∠x + ∠y + ∠z = 180 {Angle sum property of triangle}

y - 35 + y + 90 = 180

y + y - 35 + 90 = 180 {Combine like terms}

2y + 55 = 180

2y = 180 -55 {Subtract 55 from both sides}

2y = 125 {Divide both sides by 2}

y = 125 /2

∠y = 62.5°

∠x = 62.5 - 35 = 27.5°

Answer:

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. Hence, the two shorter sides created on diagonal RT ("6x-7" and "x+28" ) are equal.

We can set them equal and solve for x:

$6x-7=x+28\\6x-x=28+7\\5x=35\\x=\frac{35}{5}\\x=7$

So the side length of 6x -7 is:

6(7)-7 = 35

and the side length of x + 28 is:

7 + 28 = 35

THus, the diagonal RT = 35 + 35 = 70 units

Answer choice A is right.
