Answer:

57 degree

Step-by-step explanation:

Using cos formula again~

So AB^2=BC^2+AC^2-2*BC*AC*cosC

AB= 25.15cm

BC^2=AB^2+AC^2-2ABACcosA

Cos A=0.55

A=56.58degree

Abstract Reasoning Classify the angles that result from bisecting each type of angle.
Nadusha1986 [10]

The angles that will be formed when each angle type is bisected can each be classified as:

A. Two acute angles.

B. Two acute angles (45 degrees each).

C. Two acute angles (less than 90 degrees)

D. Two right angles (90 degrees each).

<h3>What are the Measure of the Special Angles?</h3>

An acute angle has a measure that is less than 90 degrees.

A right angle has a measure that is equal to 90 degrees.

The measure of an obtuse angle is equal to an angle measure that is greater than 90 degrees but less than 180 degrees.

The measure of a straight line angles equals 180 degrees.

With the above knowledge, we can determine what type of angle would be formed when each of the angle type is bisected. When an bangle is bisected, it is divided into two equal parts.

A. Bisecting an acute angle will result into two acute angles.

B. Bisecting a right angle will result into two acute angles (45 degrees each).

C. Bisecting an obtuse angle will result into two acute angles (less than 90 degrees)

D. Bisecting an straight angle will result into two right angles (90 degrees each).

You are running an experiment in class where you draw colored marbles out of a bag. There are
MaRussiya [10]

Answer:

32768 ways

Step-by-step explanation:

Given

Marbles = 8 marbles

Selection = 5 (with replacement)

Required

Determine the number of ways

Because it is a selection with replacement; each selection is as follows:

First = 8\ marbles

Second = 8\ marbles

Third= 8\ marbles

Fourth = 8\ marbles

Fifth = 8\ marbles

Total number of ways is then calculated as:

Total = 8 * 8 * 8 * 8 * 8

Total = 32768

Two vectors of lengths 4 and 6 have a dot product equal to 24. Which is true about the vectors?
GarryVolchara [31]

Answer:

1

Step-by-step explanation:

the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors), and returns a single number. In Euclidean geometry , the dot product of the Cartesian coordinates of two vectors is widely used.
