an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.

Answer:
Standard deviation gets smaller
Step-by-step explanation:
No. of students = 45
The class had an average of 56 words per minute (WPM) with a standard deviation of 7 WPM.
The teacher realized that the data from one student who typed 55 WPM was not entered.
So, new sum = 2520+55
New sum =2575
So, new mean =
New mean =57.22
Standard deviation is the measure of distance between observation and mean
So, if number gets closer to mean , Standard deviation gets smaller . if the numbers get bigger , Standard deviation gets bigger.
Since 55 is closer to 57.22
So, Standard deviation gets smaller
