Answer:
c=13
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
12^2+5^2=x^2
169=x^2
x=13
This is one of the few combination of triangle you should really memorize.
Answer:
1,3
Step-by-step explanation: i belive so
2(3x+5)=22+5x-3x
using associative property we shall open the parenthesis
6x+10=22+5x-3x
6x+10=22+2x
using cummutative property and additive identity property we shall put like terms together
6x-2x=22-10
4x =12
x=12/4
x=3
Answer:
113.04
Step-by-step explanation:
To find the area of a circle, you multiply 3.14 times the radius squared. To find the radius, you divided the diameter by 2. You get 6. You square 6 and get 36. Multiply that by 3.14 and you'll get 113.04 as your area.
Answer:
