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°
Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 17 ← left side is a perfect square, thus
(x - 5)² = 17 ( take the square root of both sides )
x - 5 = ±
( add 5 to both sides )
x = 5 ± 
Thus
x = 5 - 
x = 5 + 
5 + 4 - 1 = 7
7 + 4 - 1 = 10
10 + 4 - 1 = 13
And so on
Answer:
No and No
(I didn’t actually say no, I mean like both answers are no.)
I hope I was right.
Have a nice day
