Answer:
Obtuse isosceles
Step-by-step explanation:
Since this is an obtuse isosceles triangle, the two missing angles must be acute angles.

In systematic sampling, individuals are selected at regular intervals from the sampling frame.
<h3>How to explain the sampling?</h3>
Stratified sampling- In this method, the population is first divided into subgroups (or strata) who all share a similar characteristic
<u>Clustered sampling.</u>- a clustered sample, subgroups of the population are used as the sampling unit, rather than individuals. The population is divided into subgroups, known as clusters, which are randomly selected to be included in the study
<u>Simple random sampling. </u>-In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
Quota sampling--This method of sampling is often used by market researchers. Interviewers are given a quota of subjects of a specified type to attempt to recruit.

s = the number of student tickets sold
a = the number of adult tickets sold
The drama class sold 25 more student tickets than adult tickets to the fall play
s = a + 25
The class collected $660 from ticket sales:
6s + 3a = 660 divide both sides by 3
2s + a = 220
by solving the system of equations
s = a + 25
2s + a = 220
we find
s = 81.67 student tickets
a = 56.67 adult tickets
Here, we are required to determine how many <em>perfect cube divisors</em> <em>160,000</em> has.
160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
To determine how many perfect cube divisors 160,000 has;
We first need to highlight the <em>factors</em> of 160,000 as follows;
<em>(2 × 2 × 2) × (2 × 2 × 2) × 2 × 2 × (5 × 5 × 5) × 5</em>
As such, the product of numbers in each bracket yield a perfect cube; the expression above then becomes;
<em>2 × 2 × 5</em> × 8 × 8 × 125.
Therefore, 160,000 has three(3) perfect cube divisors namely;. 8, 8 and 125
