Option B:
False
Solution:
Given GF = 10, FH = 6, GH =
To verify that ΔFGH is right triangle or not:
<u>Pythagoras theorem:</u>
If the square of the hypotenuse is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
Using Pythagoras theorem,
= 10²
= 100
=
=
= 36 + 63
= 99
100 ≠ 99
Hence ΔFGH is not a right triangle.
The given statement is false.
Option B is the correct answer.
Answer:
20 rad/sec
Step-by-step explanation:
The formula we are going to use is
Where
v is the linear velocity (here given 60 ft/s)
is the angular velocity (what we sought to find)
r is the radius (which is half of diameter, hence, 6/3 = 3 ft)
<em>Plugging these numbers in, we find the angular velocity as:</em>

<u><em>Note: </em></u><em>the units is radians per second (rad/s)</em>

Correct answer 20 rad/sec

Y is congruent to X and T is congruent to S, the two triangles kiss each other.
Answer:
1/4
Step-by-step explanation:
There are 3 even numbers of the 6 numbers on a die.
(1,2,3,4,5,6) are the possible numbers. 2,4,6 are even
P( even number ) = 3/6 = 1/2
P (heads) = 1/2
Since they are independent events, we can multiply the probabilities together
P (even, heads) = 1/2 * 1/2 = 1/4
