Question

In a triangle PQR, angle QRS=a, angle PRQ=60and angle PQR=50, Find a​

Answer 1

Answer:

I don't know where S came from in a triangle, but I'll try understanding.

Step-by-step explanation:

<PRQ= 60

<QRP= a

<PQR= 50

The sum of all interior angles of a triangle is: 180 degrees

Hence,

60 + 50 + a= 180 (sum of all interior angles of a triangle is: 180 degrees)

Remember to always write the property otherwise, you may lose marks.

= 110 + a= 180

= a = 180- 110

= a = 50

Knowing this, the triangle is probably icoseles.
