21/28 is equlvilant to 7/8
Answer:
Step-by-step explanation:
We know the area of a triangle is B*H/2. For Triangle ABC, the area is 75. So the equation formed is:
15*h/2 = 75
15*h = 150
h = 10.
Now we know the height for the bigger triangle is 10. Since the scale factor from 15 --> 3 is 5, the height for triangle EFG is 2 because 10 divided by 5 is 2. Since we now know the height of the triangle is 2 and the base is 3, we can form the equation:
3*2/2 = Area
6/2 = Area
3 = Area
We know the area is 3. The key thing was we didn't divide triangle ABC with 5 because the area would not be the same. We must use the equation and from this we will get the correct area.
Its eliminating. You will need to make the conditions on each side just as much alike as possible in the two equations for simple thought method
Answer:
undefined
Step-by-step explanation:
Here,
x1 = - 3
y1 = 6
x2 = - 3
y2 = 4
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 4 - 6 ) / ( - 3 - ( - 3 )
= - 2 / 0
= undefined
we are given
we can use exponent formula
now, we can use this formula
we can add exponent
and we get
So, option-B.......Answer
