Answer:
= x
Step-by-step explanation:
In right triangles the sum of square length of two legs is equal to square length of hypotenuse:
7^2 + 8^2 = x^2
49 + 64 = x^2 add like terms
113 = x^2 find the root for both sides
1+1^22+9^1=?
1^22 = 1
9^1 =9
1 + 1 + 9
11
if you set b and a to the same number it would be equal to 2
(33-17.3)-(121.4+3)
The answer is -108.7
Hope this helps!
