Question

In a triangle ABC~PQR then a =30 and b=60 then r=

Answer 1

Answer:

30+60=90

Step-by-step explanation:

180-90=90 so answer is 90

Answer 2

given that

∆ABC~∆PQR

then all angles are same.so

<A=<P. , <B=<Q. AND <C=<R

SO <A=30 <B=60

the sum of interior angles in a triangle =180

then <C=180-90

<C=90

so <c=<R

so<R=90
