Answer:
126
Step-by-step explanation:
7x6=42
7x6÷2=42÷2=21
42+21=63
63+63=126
Options A,B and D. The correction about the area of the triangle are
- The apothem can be found using the Pythagorean theorem.
- The apothem can be found using the tangent ratio.
- The length of the apothem is approximately 2.5 cm.
<h3>How to solve for the length of the Apothem using the Pythagoras theorem</h3>
Firstly this is an equilateral triangle
3 of the sides have the length of 8.7cm
b = half of 8.7
= 4.35cm
To get A we have
a² + b² = c²
a² + 4.35² = 5²
When we solve this out we would have
a² = 25 - 18.9225
a ≈ 2.5 cm.
Hence we have proved that the first option is correct.
<u>For B,</u>
In an equilateral triangles, each of the angles = 60 degrees
60/2 = 30 is the angle that is made from the base
<h3>using tangent ratios </h3>
a / 4.35 = tan 30
then a = 4.35 tan 30
This would also give us an approximate of 2.5
For D
The calculations we have done based on the statements in A and B shows that D is correct as 2.5.

The total amount that must be repaid will be "$18,630".
Given values are:
Loan amount,
Interest rate,
Time to repay,
As we know, the formula of simple interest,
→ 
By substituting the values, we get
→ 
→ 
→ 
($)
hence,
The total amount must be paid will be:
= 
= 
= 
($)
Thus the above approach is correct.

First plot those points. You should see a *right* triangle, with sides:
4 vertical and 6 horizontal
So, the circumcenter is the mid point of the hypotenuse of the triangle, because it is a right triangle (otherwise is really harder).
The mid point of F and E:
CIRCUMCENTER = (F+E)/2 = ( (1,5)+(7,1) ) / 2 = (8,6)/2 = (4,3)
ANSWER (4,3)
