Justify the congruence between each of the following pairs of triangle.

Fantom [35]

Answer:

Refer to the attachment for the labelling of the triangles.

In △ABC & △PQR,

∠A = ∠R (equal pair of angles)

∠B = ∠Q (equal pair of angles)

AC = PR (equal pair of sides)

•°• △ABC ≅ △RQP (Angle-Angle-Side congruence property → AAS property)

Use the Pythagorean theorem to find the unknown side of the right triangle.

Nesterboy [21]

The length of hypotenuse is 39.

Step-by-step explanation:

Given,

Vertical side = a = 15

Horizontal side = b = 36

Hypotenuse = c

Using pythagorean theorem

$a^2+b^2=c^2\\(15)^2+(36)^2=c^2\\225+1296=c^2\\1521=c^2\\c^2=1521$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{1521}\\c=39$

The length of hypotenuse is 39.
