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

In ΔPQR, the measure of ∠R=90°, QR = 8 feet, and RP = 3.9 feet. Find the measure of ∠P to the nearest degree.
Kipish [7]

Answer:

64°

Step-by-step explanation:

Check the attachment for the diagram. Since the triangle has one of its angle as 90°, it is a right angled triangle.

Using the SOH CAH TOA trigonometry ratios:

Since ∠P is opposite to side QR,

QR = opposite side = 8ft

RP = adjacent side = 3.9ft

According to TOA

Tan∠P = Opposite/Adjacent = QR/RP

Tan∠P = 8/3.9

Tan∠P = 2.05

∠P = arctan 2.051

∠P = 64°
