WHAT IS ALGEBRA??

 Alegbra is finding the unknown and having a balance.

 

WHAT IS THE ALGEBRA FORMULA??

The formula for algebra that we use is a2 + b2 = c2. This formula is used for solving a triangle's angle.

 

FINDING THE SIDES OF THE TRIANGLE..........

If you're trying to find the side of "C", then your formula would be like this : c2 = a2 + b2.

If you're trying to find the side of "B", then your formula would be like this : b2 = c2 - a2.

If you're trying to find the side of "A", then your formula would be like this : a2 = c2 - b2.

 

Do you actually know what the letters " a, b and c" really is? Well "a" means it's the altitude, "b" is the base, and "c" is the hypotemuse, which means the longest side.

 

HOW TO FIND "C"

 

c2 = a2 + b2

c2 = 7 squared + 9 squared

c2 = 49 + 81

c2 = 150

c  = /150

c  = 12.24cm

 

 

 

 

 

HOW TO FIND "B"

 

b2 = c2 - a2

b2 = 8 squared - 3 squared

b2 = 64 - 9

b2 = 55

b  = /55

b  =  7.41 cm

 

 

HOW TO FIND "A"

 

a2 = c2 - b2

a2 = 10 squared - 5 squared

a2 = 100 - 25

a2 = 75

a  = /75

a  = 8.66

 

 

 

HINT!!!!!!!!!!!!!!!!

 

 ALWAYS PUT THE UNIT VALUE SIGN!!!!!!!!!!

 

 

HEY!! TRY OUT OUR JEOPARDY GAME!! 

 

 

 

 

 

 

 

 

 

 

 

Wrong!

Correct!
