Answer:
x+40 or 40+x
Step-by-step explanation:
It doesn't tell you the amount of money she's saved before so you make it a variable. I used x.
After mowing she got $40 and decided to add that to her savings.
You already know her savings before, x, and now you have $40.
So you end up writing the expression x+40 or 40+x.
Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43
~Hello There!~
Anything to a negative power, turns it into 1 over that number.
Therefore ![49^{-\frac{1}{2} } = \frac{1}{49\frac{1}{2} }](https://tex.z-dn.net/?f=49%5E%7B-%5Cfrac%7B1%7D%7B2%7D%20%7D%20%20%3D%20%5Cfrac%7B1%7D%7B49%5Cfrac%7B1%7D%7B2%7D%20%7D)
Anything to the power of a half, means you have to square root it.
Therefore, the first part is now ![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
When you have a fraction as a power and both numbers are above one:
You must 'root' it by the denominator and put it to the power of the top number.
Therefore, ![\sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%20%3D%204)
= 16
Now we have:
![\frac{1}{7} * 16](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D%20%2A%2016)
Simply divide 16 by 7 to get the answer:
2.285714
However, since it is a long number, you can just leave it as ![\frac{16}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B7%7D)
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

A triangles angles add up to 180 degrees so
88 + 77 + 8 has to equal 88 or the triangle is impossible and
88 + 77 + 8 = 173
so the triangle would be impossible.
