. Triangles Q R P and X Y Z are congruent. Angle P Q R is 72 degrees. The lengths of sides A P and P R are 2.5 inches. Angle X Y Z is 36 degrees. The length of side X Y is 1.4 inches.

What is the perimeter of ΔYXZ?

A) 3.5 in.
B) 5.3 in.
C) 6.4 in.
D) 7.8 in.

6.4in (C)

Step-by-step explanation:

Find attached the diagram gotten from the information.

∠PQR = 72°

∠XYZ = 36°

PQ = PR = 2.5in

XY = 1.4in

To determine the perimeter of ΔXYZ, we would sum the sides of all the triangles together.

Since Triangles Q R P and X Y Z are congruent.

ZY = PR = 2.5in

ZX= PQ = 2.5in

Perimeter of ΔXYZ = ZX+ XY + ZY

Perimeter of ΔXYZ = 2.5in +1.4in +2.5in

Perimeter of ΔXYZ = 6.4in (C)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
