Answer:
m∠B = 95°
Scalene
Step-by-step explanation:
by definition, internal angles in a triangle must add up to 180°
in this case,
∠A + ∠B + ∠C = 180°
we are given ∠C = 55° and ∠A = 30°
30° + ∠B + 55° = 180°
∠B = 180 - 55 - 30 = 95° (Answer)
We can see that all 3 angles of the triangle are different. And hence we can conclude that all 3 sides of the triangle are different length (i.e it is not equilateral or isosceles). Hence it is a scalene triangle.
The frequency is how often something occurs. Here 15. It occurred 15 times that the participants scored in the interval given.
The relative frequency (expressed as a percent) looks at how often something occurred relative to the overall occurrences. Here 15/60 = 1/4 = 25%
The relative frequency is 25%
Using the proportions given in the table, it is found that the percentage of the Northlake residents surveyed that want a new dog park is:
B. About 58%.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Multiplying a proportion by 100%, a percentage is found.
Looking at the table, 25% are Northlake residents(which is 43% of the surveyed) who want a new dog park, hence the percentage is given by:
p = 25/43 x 100% = 58%.
Hence option B is correct.
