Answer:

x=5

Step-by-step explanation:

Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:

x^2-7=4x-2

x^2-4x-5=0

(x-5)(x+1)=0

x=5,-1

Since a side of a triangle can't be negative, the answer is 5.

In a right triangle PQR,∠Q=90
Nikitich [7]

Answer:

a) PR = 17 cm, b) QR = 6 cm

Step-by-step explanation:

∠Q=90, so PQ and QR are legs, and PR is hypotenuse.

Pythagorean theorem PQ² + QR² = PR²

a) PQ² + QR² = PR²

    8² + 15² = PR²

PR² = 289

PR = 17 cm

b) PQ² + QR² = PR²

   8² + QR² = 10²

64 + QR² = 100

QR² = 36

QR = 6 cm
