Mathematics
1 answer:
tekilochka [14]3 years ago
6 0

Answer:

Step-by-step explanation:

The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/  But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length,  knowing that.. we can set the two expression equal to each other

3x - 10 = 2x

now solve for x

3x - 10 -2x = 2x - 2x  ( subtracting 2x from both sides )

3x - 2x - 10 = 0

x - 10 = 0

x - 10 + 10 = 0 + 10

x = 10    ( yay)

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? square root of 8 units 4 units squa
ycow [4]
By the Pythagoras theorem, in a right triangle with the sides being a and b,

 a² + b² = Hypotenuse²

Hypotenuse² = 4² + 4²

Hypotenuse² = 16 + 16 = 2*16

Hypotenuse = √2 * √16

Thus, hypotenuse = 4√2

Increase 400 by 10% and then decrease the answer by 10%
makvit [3.9K]

Answer:80

Assume the number to be 400 for instance,

10% of 400 increased = 400 + ( 10/100 × 400 )

= 400 + 40 = 440

The resulting number decreased by its 10% = 400 - (10/100 × 400)

= 400 - 40 = 360

Now, net decrease = 440 - 360 = 80
