Question

solve it please kisi ka Kalyan kr do solve karke ​

Answer 1

1) 5x+20+75=180°(linear pair)

5x+95=180

5x=85

x=85/5=17

x=17

2) PQ=RQ (isosceles triangle)

 ∠P= ∠R (opposite angles of isosceles triangle are equal)

45°=45°

 ∠P+ ∠Q+ ∠R=180°(angle sum property)

45°+x+45=180°

90+x=180°

x=90°
