Answer:

Step-by-step explanation: let 2:3:5:8 be 2x,3x,5x,8x respectively .

*angles in a quadrilateral is 360 degree

*2x+3x+5x+8x=360

*18x=360

*x=360/18

*x=20

now substitute x in these:

2x=2x20=40

3x=3x20=60

5x=5x20=100

8x=8x20= 160

so these are the following angles: 40,60,100 and 160

GEOMETRY PLEASE HELP ME URGENT
Basile [38]
Converse (switch p and q)
If an angle is obtuse, then it measures 128°

This is false (a 127° angle is obtuse, but it does not measure 128°)

_____________________________________________________________

Inverse
(negations of p and q)
If an angle does not measure 128°, then it is not obtuse

This is false (a 127° angle does not measure 128°, but it is obtuse)

_____________________________________________________________

Contrapositive (negations of p and q, then switch their places)

If an angle is not obtuse, it does not measure 128°

This is true (any 128° is obtuse; no exceptions)
