Question

find angle of triangles​

Answer 1

Step-by-step explanation:

PTQ is an equilateral triangle

So <Q=<T=<P=60°

As <a=<b=<c=x

$3x = 60 \\ x = 60 \div 3 = 20$

In triangle PRS

b=20°

<R+<S+<b=180°

R+S=160

2R=160

R=80°

<f=80°

Answer 2

Answer:

if Triangle POT is equilateral

each angle will be equal to 180÷3=60 degrees

now if a= b=c

let it be x

so 3x=60

x=60÷3

=20 degrees

Step-by-step explanation:

20 degrees is the answer
