Question

If the angles of a quadrilateral are 4x, 3x + 10°, 2x + 10° and 4x + 15°, then find the measure
of each angle.​

Answer 1

Answer:

7x+10⁰,2x+10⁰

13x=25

X=25/13

Answer 2

Answer:

Step-by-step explanation:

let the angles be  4x, 3x + 10°, 2x + 10° and 4x + 15

so, 4x + 3x + 10 +2x + 10 + 4x + 15 = 360   [ quadrilateral sum 360]

                     13x + 35   = 360

                           13x = 360 -35 = 325

                               x = 325/13  = 25

s0 4x = 4 * 25 = 100

3x + 10 = 3 * 25 +10 = 85

2x  + 10 =2 * 25 + 10 = 60

 4x + 15 = 4 * 25 + 15 = 115

hope it helps you very well
