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

They are just in the opposite side
Answer:
Step-by-step explanation:
<u>Given</u>
- DE = 3x + 2, EF = x + 5, DF = 23
<u>As per segment addition postulate</u>
<u>Substituting values:</u>
- 3x + 2 + x + 5 = 23
- 4x + 7 = 23
- 4x = 16
- x = 4
Answer:
-13/4 =n
Step-by-step explanation:
-5/2 = 3/4 +n
Subtract 3/4 from each side
-5/2 - 3/4 = 3/4 +n-3/4
-5/2 -3/4 =n
Get a common denominator
-5/2 *2/2 - 3/4=n
-10/4 - 3/4 = n
-13/4 =n
