Question

Express x in terms of p,q, and r.​

Answer 1

Answer:

$x=2p\ or\ x=180-(q+r)$ and thus $x=2p=180-(q+r)$

Step-by-step explanation:

We know the angle ∠$QXR$    is the twice of the angle ∠$QPR$

therefore $x=2p$

Also, we know that the sum of angles inside a triangle is $180$°,

therefore $x=180-(q+r)$

Combining these two equations we can write

$2p=180-(q+r)$

Hence the answer
