2(x+y)=24(x=rows and y=col)
x+y=12
now x could 1,2,3,4,5,6,7,8,9,10,11 and y could be 11,10,9,8,7,6,5,4,3,2,1 respectively
Answer: original angle = 75°
Its supplement 105°
Its complement = 15°
Step-by-step explanation:
We know that,
- Sum of supplementary angles is 180 degrees.
- Sum of complementary angles is 90 degrees.
Let x be the original angle , then its supplement = 180° - x
its complement = 90° - x
As per given,
180° - x = 7(90° - x)
⇒ 180° - x = 630° - 7x
⇒ 7x- x = 630° -180°
⇒ 6 x = 450°
⇒ x = 75° [divide both sides by 6]
So, original angle = 75°
Its supplement = 180° - 75° = 105°
Its complement = 90° -75° = 15°
Hence, original angle = 75°
Its supplement 105°
Its complement = 15°
The force vector F in terms of i and j, considering it's magnitude and angle, is represented by:
<h3>How can a vector be represented in i and j notation?</h3>
Given a magnitude M and angle , the a vector V can be represented as follows:
In this problem, we have that the parameters are as follows:

Because the emperor penguin is 24 inches taller than the rockhopper, we use the equation 45 - 24 = r. (r is a variable for rockhopper penguin.)
Solve 42 - 24 = r
18 = r therefore, the height of the rockhopper is 18 inches.
We can check our answers. 24 + 18 is the height if the emperor, which is 45 inches.
| n + 7 | = 5
=> n + 7 = 5 or n + 7 = -5
=> n = -2 or n = -12
ok done. Thank to me :>
