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.
Answer:
between 5 and 6
Step-by-step explanation:
Choose 2 perfect squares either side of 28, that is
25 < 28 < 36, then
< 
< 
, thus
5 < < 6
Answer:
Solution to system is
x = 6 and y= 4
S.set={6,4}
Step-by-step explanation:
The given equations are
x + 3y = 18 ................(i)
x + 2y=14 .................(ii)
Subtracting both equation
(x+3y)-(x+2y)=18-14
x+3y-x-2y = 4
y = 4
put the value of y in equation (i)
the equation becomes
x + 3(4) = 18
x + 12 = 18
subtracting 12 from both sides
x + 12 -12 = 18-12
x =6
Solution to system is
x = 6 and y= 4
S.set={6,4}
Answer:
An angle that measures exactly 180° is known as a <u>straight</u> angle
Step-by-step explanation:
A straight angle is basically just a line. It is equal to two right angles (which are 90 degrees) and it is also half of a circle.
I hope this was helpful! If you need any more information on straight angles or any other angles, let me know! Have a lovely day! :)
