Willie left the mall and traveled toward the town hall at an average speed of 40 km/h. Gabriella left two hors later and travele

mezya [45]

Answer:

<em>3 hours</em>

Step-by-step explanation:

Given that:

Average speed of Willie = 40 km/h

After 2 hours, Gabriella traveled in opposite direction at an speed of 70 km/h.

After some time, they are 410 km apart.

To find:

Number of hours = ?

Solution:

For the first two hours, Willie traveled alone.

Formula for distance:

$Distance = Speed \times Time$

Distance traveled in two hours by Willie = $40 \times 2 = 80\ km$

Now, they both travel in opposite directions.

So the relative speed is = 40 + 70 = 110 km/h

The distance traveled by them = 410 - 80 = 330 km

$Time\ taken = \dfrac{330}{110} = 3\ hours$

Therefore, the time taken is <em>3 hours.</em>

What is the relationship between \blueD{\angle a}∠astart color #11accd, angle, a, end color #11accd and \greenD{\angle b}∠bstart

Elza [17]

Answer:

Complementary angles.

Step-by-step explanation:

Notice that $\angle a=\angle AXY, \angle b = \angle YXB$ and $\angle BXC = 90\°$ , by given.

$\angle AXB = \angle AXY + \angle YXB$ , by sum of angles.

$\angle AXB + \angle BXC = 180\°$ , by supplementary angles definition.

$\angle AXB + 90\° = 180\°\\\angle AXB = 180\° - 90\°\\\angle AXB = 90\°$

Which means,

$\angle AXB = \angle AXY + \angle YXB = 90\°$

Therefore, $\angle a + \angle b = 90\°$ , in other words, angles a and b are complementary by definition.
