Answer 2

Answer:

Given:-

Find the value of x in the given figure when ∠PQ = (2x + 60)° and ∠OQ = (3x - 40)°

To Find:-

The value of "x"

Solution:-

When ∠POR and ∠ROQ is added it gives 90°, so according to this~

$∠POR + ∠ROQ = 90°$

$2x° + 60° + 3x° - 40° = 90°$

$5x° + 20° = 90°$

Note:-

when + interchange to another side it becomes "-"

when × interchange to another side it becomes ÷

On rearranging

$5x° = 90° - 20°$

$x° = 70°/5$

Answer:-

$x = 14°$
