Question

If x°, (x + 10)°, (x + 20)° and (x + 30)° are the angles of a quadrilateral, then the measure of

greatest angle is​

Answer 1

Answer:

biggest anlgle is 105

please rate it, hope it helps

Step-by-step explanation:

x+x+x+x+10+20+30 = 360

4x=360-60

x=300/4=75

Answer 2

$x + x + 10 + x + 20 + x + 30 = 360 \\ 4x + 60 = 360 \\ 4x = 300 \\ x = 75$

the greatest angle is 75+30 = 105°.
