Answer:
<em>66°</em>
Step-by-step explanation:
mJK = ( 6x - 45 )°
mJH = ( x + 20 )°
mJK = mJH
6x - 45 = x + 20
5x = 65
x = 13
mHK = ( x + 20 )° + ( 6x - 45 )°
<em>mHK =</em> 2 × 33° = <em>66 </em>°
Given that the number, 5,83_ has 2 as a factor.
It implies that the number 5,83_ is an even number
The number contains
5 thousands
8 hundreds
3 tens
? units
The possible units of an even number are 0, 2, 4, 6, and 8
Therefore, the unknown digit could be 0, 2, 4, 6, or 8
Answer:
1
Step-by-step explanation:
when x is by itself, that means there is a one in front
Answer:
area will be four times the first area
Step-by-step explanation:
the diameter of the first sphere=d
therefore radius=d/2
=r
the diameter of the second sphere becomes 2d
therefore the radius of second sphere=2r
area of a sphere=4×pi×r^2
the ratio of the two spheres=(4pi(2r)^2)/(4pir^2)
=(4pi4r^2)/4pir^2
cancelling 4pir^2, you get 4:1
therefore the area of the second sphere is 4 times the first one
Step-by-step explanation:
1 + - 1 can also be written as 1 - 1.
1 + - 1
= 1 - 1
= 0
Hence proved.
