The 3 inside angles of a triangle need to equal 180 degrees.
You are told two of the angles are 106 and 59.
To find the 3rd angle subtract the 2 known angles from 180:
180 - 106 - 59 = 15 degrees.
The one on the left side: 180 - 33 - 114 = 33
The one on the right: 180 - 90 - 73 = 17

Step-by-step explanation:
Average systolic blood pressure = x = 130
Standard deviation = s = 6
We are to find interval that represents the systolic blood pressure of middle 99.7% of the males.
According to the empirical rule:
a) 68% values lie within 1 standard deviation of the mean
b) 95% values lie within 2 standard deviation of the mean
c) 99.7% values lie within 3 standard deviation of the mean
So, 99.7% value will lie within 3 standard deviations from the mean.
We can express this range as:
( x - 3s, x + 3s)
= (130 - 3(6), 130 +3(6))
= ( 130 - 18, 130 + 18)
= ( 112, 148 )
Thus the interval from 112 to 148 contains the systolic blood pressure of middle 99.7% of the males in the certain town
