Answer:
y = 3/5x + 12/5
Step-by-step explanation:
y = mx + c
0 = 3/5 ( -4 ) + c
0 = -12/5 + c
12/5 = c
y = 3/5x + 12/5
The length of the x in the diagram is 12.
We can set up the following equation using the similar triangles that are created when you have an altitude in a right triangle.
If you subtract 16 from 25, you get 9, which is the length of the segment next to the 16.
x^2 = 16(9)
x^2 = 144
x = 12
Answer:
x = 7°
<GDH = 112°
<FDH = 192°
<FDE = 135°
Step-by-step explanation:
If DE bisects <GDH this means that <GDE = <EDH
Given <GDE = (8x+1)° and <EDH = (6x+15)° then;
8x+1 = 6x+15
8x-6x = 15-1
2x = 14
x = 7°
Since <GDH = <GDE + <EDH
<GDH = 8x-1+6x+15
<GDH = 14x+14
<GDH = 14(7)+14
<GDH = 98+14
<GDH = 112°
For <FDH,
Note that sum of angle on a straight line is 180°
<FDH = <FDG + <GDE + <EDH
<FDH = <FDG + <GDH
<FDG = 180-(43+8x+1)
<FDG = 180-44-8x = 136-8x
<FDH = 136-8x+112
<FDH = 248-8x
<FDH = 248-8(7)
<FDH = 248-56
<FDH = 192°
For <FDE;
<FDE = <FDG + <GDE
<FDE = 136-8x+8x-1
<FDE = 135°
1*5.5=5.5, so 6*5.5=33,
so 5.5 cm is 33 m in real life
