Answer:
The height of the triangle is 5.2 inches
Step-by-step explanation:
we know that
An <u>equiangular triangle</u> is a triangle where all three interior angles are equal in measure
Remember that an equilateral triangle has three equal sides and three equal interior angles
so
An equiangular triangle Is the same that an equilateral triangle. The measure of its interior angles is equal to 60 degrees
Let
h ----> the height of triangle
b ---> the length side of the triangle
Applying Pythagoras Theorem
we have
substitute
see the attached figure to better understand the problem
Since we want to estimate the percentage of adults in the town who belong to a gym. We should take a random sample from the town itself because a store’s adult customers, or their friends, or first 20 customers every day for one week, or adults at the local park might not represent better sample for survey.
Therefore, Take a random sample of adults in the town, and ask each person whether he or she belongs to a gym. Calculate the percentage of the total who say “yes.”
Hence, option D describes a method that will help the marketing department accurately estimate this percentage.
Answer:
#5: Equivalent
#6: Not Equivalent
1. 3x+6
2. 4y-4
3. x²+6x
4. xy+4x
5. 3x²+3xy-3x
Step-by-step explanation:
for #6 the equivalent: 2x(x+3)= 2x²+6x
