Answer 1

Answer:

C and A

Step-by-step explanation:

For the triangle to be isosceles then the legs are congruent, that is

XZ = XY , substitute values

5x - 1 = 3x + 5 ( subtract 3x from both sides )

2x - 1 = 5 ( add 1 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3 → C

(10)

The diagonals of a square bisect each other

Calculate PR using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2-y_{1})^2 }$

with (x₁, y₁ ) = P(0, 0) and (x₂, y₂ ) = R(6, - 8)

PR = $\sqrt{(6-0)^2}+(-8-0)^2$

     = $\sqrt{6^2+(-8)^2}$

     = $\sqrt{36+64}$

     = $\sqrt{100}$

     = 10

Then

PT = 0.5 × 10 = 5 → A
