The measures of complementary angles have a sum of 90 degrees.Angle A and angle B are complimentary, and their measures have a d

777dan777 [17]

Answer:

The measure of the angles are 55° and 35°

Step-by-step explanation:

Sum of two angles that are complement of each other are 90.

The angles are A and B, so we can write:

A + B = 90

Also,

The difference is 20. Let A be the greater of them, so we can write equation 2 as:

A - B = 20

Now, we add up both equations, eliminate B and solve for A first:

A + B = 90

A - B = 20

---------------

2A = 90 + 20

2A = 110

A = 110/2

A = 55

And now the measure of B:

A + B = 90

55 + B = 90

B = 90 - 55

B = 35

While playing baseball, sofia takes note of the extreme vectors for which she bats. what is the angle between her two extreme ba

k0ka [10]

The angle between the two extreme vectors of Sofia bats is 74.60 degrees.

In this question,

The angle between two vectors will be deferred by a single point, which is called as the shortest angle at which we have to turn around one of the vectors to the position of co-directional with another vector.

The extreme vectors of Sofia bats are $\vec u = < -8, 12 >$ and $\vec v = < -8, 12 >$

The angle between the vectors is

$\theta = cos^{-1} \frac{\vec u.\vec v}{||\vec u|| ||\vec v||}$

The dot product is calculated as

$\vec u. \vec v = (-8)(13)+(12)(15)$

⇒ $-104+180$

⇒ 76

The magnitude can be calculated as

$||\vec u|| = \sqrt{(-8 )^{2} +(12)^{2} }$

⇒ $\sqrt{64+144}$

⇒ $\sqrt{208}$

$||\vec v|| = \sqrt{(13 )^{2} +(15)^{2} }$

⇒ $\sqrt{169+225}$

⇒ $\sqrt{394}$

Thus the angle between the vectors is

$\theta = cos^{-1} \frac{76}{(\sqrt{208} )(\sqrt{394} )}$

⇒ $\theta = cos^{-1} \frac{76}{\sqrt{81952} }$

⇒ $\theta = cos^{-1} \frac{76}{286.27 }$

⇒ $\theta = cos^{-1} (0.2654)$

⇒ $\theta=74.60$

Hence we can conclude that the angle between the two extreme vectors of Sofia bats is 74.60 degrees.
