Question

help! mee I need help I'm in trouble​

Answer 1

1. X=2 (given)
Substituting x in 4.4x-3.8=5

4.4*2-3.8=5
8.8-3.8=5


2. Let the ratio 2:3:4 be 2x 3x and 4x

Sum of all angles of triangle =180 degree
2x+3x+4x=180 degrees
9x = 180 degrees
X= 20 degrees

So 2x=40 degrees
3x=60 degrees
4x=80 degrees


3. Let the ratio 1:3 be 1x and 3x
A/c to the ques
3x-1x=40
2x=40
X=20

3x = 60. 1x=20



4. Let the ratio 2:3:5:8 be 2x,3x,5x and 8x


Sum of all angles of a quadrilateral = 360 degrees
2x+3x+5x+8x=360 degrees
18x=360 degrees
X= 20 degrees


2x=40 degrees,3x=60 degrees,5x=100 degrees and 8x=160 degrees
