Answer:

The answer is 2.077  ×  10 ^-4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps!

ΔABC and ΔXYZ are similar triangles. If BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4, find the value of x.
Nat2105 [25]

Solution:

we are given that ΔABC and ΔXYZ are similar triangles.

As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.

Here we have

BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4

So we can write

\frac{x+9}{x+5}= \frac{x+7}{x+4}\\&#10;\\&#10;(x+9)(x+4)=(x+7)(x+5)\\&#10;\\&#10;x^2+13x+36=x^2+12x+35\\&#10;\\&#10;13x-12x=35-36\\&#10;\\&#10;x=-1\\&#10;\\

Hence then value of x=-1.
