3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5
Angle on top is x+8=42.5+8=50.8
Angle on the bottom is 3x+2=3•42.5+2= 129.5

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Answer:
$815
Step-by-step explanation:
Given data
Principal= $500
Rate= 9%
TIme= 7 years
The simple interest formula is
A=P(1+rt)
substitute
A= 500(1+0.09*7)
A=500(1+0.63)
A= 500*1.63
A=$815
To obtain the sample, one can choose the names of 6 students out of a hat from the students in the class using random sampling.
<h3>What is random sampling?</h3>
It should be noted that a simple random sample is a subset of a statistical population where each member of the subset has an equal probability of being chosen.
Systematic sampling is when the sample members from a larger population are selected based on a fixed, periodic interval. If you want to select a random group of 6 students from a population of about 60 using systematic sampling, every 10th person on the list is selected.
