Use Pythagorean theorem to find isos Find the value of s in the isosceles triangle shown below.
45
745
3
І
Choose 1

x = 12 or

Step-by-step explanation:

Find the length of x for one side of the triangle first. To do this, use the Pythagorean Theorem which states: a² + b² = c² or in this case c² - a² = b². c² is 45 and a² is 3*3 or 9. Subtract 45-9 to get 36. Find the square root of 36 to get 6. The opposite side is also going to have a missing side length of 6 so add 6+6 to get 12 as x.

Hope it helps!

Step-by-step explanation:

Let ABC be isoceles triangle and O be center of side x

Since area (ABO)= area (BCO)

IN TRIANGLE ABO

BY PYTHAGOREAS THEOREM

BO=

BO=✓36=6

Since BO =CO=6

x=BO+CO=6+6=12
