if a=5 and b=12 than what will be c?

Question

use you brain

Answer 1

c=19.

(You have not given any geometrical figure or any relation between a,b or c.
So, i can assume the series:
LIKE:(a,b,c,d,e,f,g,..........,z)
comparing with another series:
LIKE:(5,12,19,26,33,......180)
SO THAT
b-a=7
c-b=7
.
.
.
.
.
.
z-y=7.)
(By geometry we may use the pythagorus theorem to explain giving a^2+b^2=c^2 means 5^2=25; 12^2=144 hence c^2=25+144=169
now c= sqrt 169=13 )

Answer 2

a=5(0+5)
b=12(5+7)
c=21(12+9)

Answer 3

there are a few answers !!

Consider a, b, and c as vectors

if A= 5 and B = 12 then when we added w get C = A+B = 17

when subtracting A = 5 and B = 12 we can also get C = A-B = -7

or B-A = 7

using the pytharogeous way

C^2 = A^2 + B^2

C = 13

these are cases when they A and B are opposite to each other or in the same direction , in perpendicular to each other

Answer 4

If you use the Pythagorean Theorem,

a^2 + b^2 = c^2

Plug in your numbers:
5^2 + 12^2 = c^2

Square the 5 and 12
25 + 144 = c^2

Add
169 = c^2

Square root both sides
c = 13

Answer 5

If a, b, c are the sides of a right angle triangle
Then, by the pythagorean theorem

a^2 + b^2 = c^ 2

after simplliy c = 13

Answer 6

I don't use my brain but the answer is c=13

Answer 7

a=5 and b=12, which means that b=a+7

so i think c=b+7 or else c=a+7+7

final answer: c=19

Answer 8

If c=a+b, c=17
If c=ab, c=60
if c is the hypotenuse of a right triangle whose legs are a & b, c=13

Answer 9

c=a+b
c=5+12
c=17

Answer 10

u have not specified any formula for c

using a and b u can find an area of a triangle
length of hypotenues of a rht angled triangle
Area of a Rectangle
