Answer:
Last answer x=−6 if you want steps i can show you have a nice day i hope it is helpful
So first convert to improper fractions
7 and 7/8=7+7/8=56/8+7/8=63/8
3 and 1/4=3+1/4=12/4+1/4=13/4
so nowe we have
63/8+13/4
convert bottom number to same
which is 8
13/4 times 2/2=26/8
now we have
63/8-26/8=37/8=4 and 5/8
answer is 4 and 5/8
Answer:
x = 85
Step-by-step explanation:
The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,
![a^2 + b^2 = c^2](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20c%5E2)
Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.
Substitute in the given values and solve,
![13^2 + 84^2 - x^2\\\\169 + 7056 = x^2\\\\7225 = x^2\\\\85 = x](https://tex.z-dn.net/?f=13%5E2%20%2B%2084%5E2%20-%20x%5E2%5C%5C%5C%5C169%20%2B%207056%20%3D%20x%5E2%5C%5C%5C%5C7225%20%3D%20x%5E2%5C%5C%5C%5C85%20%3D%20x)
