Question

The measures of the angles of a quadrilateral are (3x + 20°, (4x + 15)°, (3x – 5)° & (4x
Find the difference between the biggest and the smallest angle.​

Answer 1

Answer:

Step-by-step explanation:

(3x+20)+(4x+15)+(3x-5)+(4x-20)=360

14x+10=360

14x=360-10=350

x=350/14

=25

Therefore the angles are :

95,115,70,80

Difference=115-70=45
