Answer:

The correct answer is last option 3√2 units

Step-by-step explanation:

From the figure we can see that two small right angled triangle.

These two triangle combined to form a large right angled triangle.

To find the value of x

Consider the small triangle with hypotenuse x and one side 3 units.

The angles of this triangle be 45°, 45° and 90°, then the sides are in the ratio 1 : 1 : √2

Therefore we can write,

3 : 3 : x = 1 : 1 : √2

x = 3√2

The correct answer is last option 3√2 units

D=rtthe distances are not equal, but they add up to a total of 400 milesone bus goes 55mph times t so that is 55t (that represents the distance in one direction)the other bus goes 45 mph,so that is 45t (that represents the distance in the other direction)the total distance is 400, so the equation is distance one direction + distance the other direction = 400your equation is 55t + 45t = 400 100t = 400 t= 4 hoursso after 4 hours they will be 400 miles apart

The value of x is 20.

Solution:

Sides of one triangle are 2x – 4 and 39.

Sides of another triangle are x + 6 and 24.

Property of similar triangle:

If two triangles are similar then their corresponding angles are congruent and the corresponding sides are in the same ratio.

$$\frac{2x-4}{24} =\frac{39}{x+6}$
