Answer in numbers only and the correct number of significant figures. If answering in scientific notation, do
as follows(with correct number of sigfigs.) Ex. 1.11x102 for 111

step-by-step explanation:

12475909

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
