In order to find the shaded region the first thing you have to do is find the area of the two small triangles, then find the area of the big triangle. Subtract the area of the small triangles from the big one and that is the area.

Step one: 11×12=132

Step two: 132÷2= 66

Step three: 66+66=132 (because there is two small triangles with same dimensions)

Step four: 40×15=300

Step five: 300-132=168

Answer 168m^2

Answer: 14/45

Step-by-step explanation: The probability that they first event will occur is 2/10. The probability that the second event will occur is 1/9. If you multiply those like it says in the hint you will get 14/45. (I think this is right)

If the second hand of a clock has a length of 10 cm, find the distance the tip of the second hand travels in 45 seconds. Give an

UkoKoshka [18]

The distance traveled by the second hand of the clock is 0.471 m.

<h3 />

To calculate the distance the tip of the second hand of the clock travel in 45 seconds, we use the formula below.

<h3>Formula:</h3>

L = 2πr∅/360.................. Equation 1

<h3> Where: </h3>

L = distance traveled by the tip of the second hand.
r = Length of the second hand
∅ = angle formed by the second hand of the clock
π = pie

From the question,

<h3>Given:</h3>

r = 10 cm = 0.1 m
∅ = (360×45/60) = 270°
π = 3.14

Substitute these values into equation 1

L = 0.1×2×270×3.14/360
L = 0.471 cm.

Hence, The distance traveled by the second hand of the clock is 0.471 m

Given:

ΔONP and ΔMNL.

To find:

The method and additional information that will prove ΔONP and ΔMNL similar by the AA similarity postulate?

Solution:

According to AA similarity postulate, two triangles are similar if their two corresponding angles are congruent.

In ΔONP and ΔMNL,

$\angle ONP\cong \angle MNL$ (Vertically opposite angles)

To prove ΔONP and ΔMNL similar by the AA similarity postulate, we need one more pair of corresponding congruent angles.

Using a rigid transformation, we can prove

$\angle NOP\cong \angle NML$

Since two corresponding angles are congruent in ΔONP and ΔMNL, therefore,

$\Delta ONP\sim \Delta MNL$ (AA postulate)

Therefore, the correct option is A.
