Measure of angle 5 i.e. m∠5 = 50°
<h3>
What is measurement of an angle ?</h3>
The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.
<h3>
How to find angle measurement ?</h3>
As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.
In the question,
Let given angle is ∠8.
Given, ∠8 = 50°
Now, according to vertical angle property
∠5 = ∠8
therefore, ∠5 = 50°
Thus, m∠5 = 50°

Find measure m∠5
Answer:
9 beads are purple
Step-by-step explanation:
we know that
To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple
so

therefore
9 beads are purple
Another way to solve the problem is convert the fraction in percentage
we have

so
If the total are 18 beads
50% is 9 beads
therefore
9 beads are purple
