The measure of the angles shown is 90 degrees
<h3>Lines and angles</h3>
A line is defined as the shortest distance between two points while the point where two lines meet is known as an angle.
From the given diagram, the sum of both adjacent angles is supplementary to have:
x + 96 + 96 + x = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -6
Substitute the value of x into the expression
<d = x + 96
<d = -6 +96
<d = 90 degrees
Hence the measure of the angles shown is 90 degrees

Set up a proportion
3/7/12 = 1/x
3/7x = 12
x = 28
28 - 12 = 16
16 are left

It just subtraction
Answer:
Option A
Step-by-step explanation:
A type I error is committed when a researcher rejects the null hypothesis when it is actually true.
The null hypothesis is: U <= 50%
The alternative is: U > 50%
Thus, the principal could have committed an error by rejecting null hypothesis and concluding that more than 50% of students want earlier lunch, when in actuality 50% or less want earlier lunch.
