Question

Find the value of x in given figure​

Answer 1

x=60°

because, the sum of all interior angles of triangle will be always 180°.

solution

90°+30°+x=180°

120°+x=180°

x=180°-120°

x=60°

Answer 2

Answer:

here in ∆PQR

angle P=90°(given as perpendicular)

angle Q=30°

angle R=?

we know

angle P+ angle Q+ angle R=180°(sum of all interior angles of a triangle)

90+30+angle R=180

120+x=180

x=180-120

x=60°
