Question

Find the value of x in the isosceles triangle shown below

Answer 1

X=10 you’ll have to break down your equation to solve the square root.

Answer 2

x = 10

Explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

`√(74) ^(2)` =
`7^(2)` +
`((x)/(2)) ^(2)`

74 = 49 +
`(x^(2))/(4)`

74 - 49 =
`(x^(2))/(4)`

25 =
`(x^(2))/(4)`

therefore, x =
`√(25*4)` =
`√(100)` = 10
