Question

If triangl PQR is similar to triangle XYZ, angel Q=50 degree and angel R=70 degree ,then angel X +angel Y is equal to

Answer 1

Answer:

angle Q=50

angleR=70

then angle P=60 by angle sum property

Step-by-step explanation:

by AAS PROPERTY BOTH THE TRIANGLE =

angle Q=angle Y

angle P=angle X

X+Y=50+60

=110°.

Answer 2

In ∆ PQR and ∆ XYZ ,

PQ = XY ,
QR = YZ ,
RP = ZX,

By SSS Congruence ,
∆ PQR =~ ∆ XYZ

By CPCT ,
< Q = < Y
50° = <Y

<R = <Y
70° = <Y

In ∆PQR ,
< P + < Q + < R = 180°
< P = 60° = < X

< X + <Y = 60° + 50°
= 110°
