i need an explainer and to show my work. i will give brainliest answer

A)144km/h

B)5.4km/h

Step-by-step explanation:

A) 1m=0.001km

40m= 0.04km/s

0.04kmX60s=2.4km/min

2.4kmX60min= 144km/h

B)1.5m= 0.0015km/s

0.0015kmX60s=0.09km/min

0.09kmX60min= 5.4km/h

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.
