Yes, HJ = 30 ft.
It tells us that triangle DEF = triangle GHJ.
By seeing this we know without looking at the triangles that EF is going to be the same as HJ because when they say a figure is the same as another and list the letters such as 'DEF' and 'GHJ' they will list them in the same order.
So
'DEF' = 'GHJ' we get:
'DE' = 'GH'
'EF' = 'HJ'
And we can do the last and first letters:
'FD' = 'JG'
And since we know 'EF' = 'HJ' and that they already told us 'EF' was 30, we know HJ will be 30.

86-49=37
Answer:
X= 50°
Y= 70°
Z= 30°
BDE= 30°
2BDE= 60°
Step-by-step explanation:
(2x -70 )+z+(2x+20)=180...(sum of angle on a straight line)
2x -70 = BDE... alternate angles
Y + (2x-70)+(50+x-20) = 180...(sum of angles in a triangle)
X-20 = z ... alternate and opposite angles
(2x -70 )+z+(2x-+20)=180
2x-70 + x-20 +2x +20= 180
5x -70= 180
5x = 250
X= 50°
X-20 = z
50-20= z
30° = z
2x -70 = BDE
2(50) -70 = BDE
100-70 = BDE
30°= BDE
Y + (2x-70)+(50+x-20)
Y + 100-70 +50 +50 -20 = 180
Y + 200-90=180
Y= 70°
2BDE = 2*30
2BDE= 60°
Answer:
2.f(x)=2^4x
Step-by-step explanation:
16^x
We can rewrite 16 as 2^4
2^4^x
We know that a^b^c is equal to a^ (b*c)
so 2^(4*x)
2^(4x)
