Answer:
13
Step-by-step explanation:
A^2+B^2=C^2
5=A 12=B X=C
C is is always the longest side of a right triangle.
In triangle
x²=5²+12²
x²=25+144
x²=169
x= root of 169
x=13
No it can't
In mixed number form it's 1 7/8
23°
23° because AD divide BAC into 2 equal parts
48 is the even number
81 is the square number
13 43 23 are the prime numbers
multiply everything by 8
2x+16 = -5x-40
-16 on both sides
2x = -5x-56
+5x on both sides
7x = -56
x=-8
so the first option
