Answer:
h = 12 m
Step-by-step explanation:
Sides of the triangle are proportional.
(3.6 m)/(1.2 m) = h/(1.2 m + 2.8 m)
(4 m)(3.6/1.2) = h . . . . . multiply by 4 m
h = 12 m
1. x=4
6x-3x=12
3x=12
x=4
2. x=4
3x-5=x+3
3x=x+8
2x=8
x=4
3. x=20
1/2x+1/5x=14
7/10x=14
7x=140
x=20
4. x=2
2.5x+1.0x=7
3.5x=7
x=2
Ok so... what wait weres the pic??
