Question

PQRS is a quadrilateral whose angles are (2x+10)°, (3x-15)°, (5x-5)°and (4x+20)°respectively.
find the angles of PQRS.
pls give an explanation...... ​

Answer 1

Answer:

Hey mate here is the answer

Step-by-step explanation:

we know that sum of all angles of a quadrilateral is 360°

=2x+10+3x-15+5x-5+4x+20=360

=14x+10=360

=14x=360-10

=14x=350

=x=25

angle P=2x+10

=2*25+10=60°

angle Q=3x-15

=3*25-15=60°

angle R=5x-5

=5*25-5=120°

angle S=4x+20

=4*25+20=120°
