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.

Answer: 1. 5=(x+20)
2. You cannot factor 3x+112. If you divide these two, you will get a decimal.
Step-by-step explanation:
1. Factor 5x+100
Answer is 5=(x+20)
Answer:
B) x = -4
Step-by-step explanation:
equation in the form of x=<em>some_constant_number </em>will give you a vertical line, which will be perpendicular to the horizontal line MN
Answer:
Step-by-step explanation:
x^2-x-20
Is that what you are looking for?
You do y1-y2 / x1-x2. So, it would be 3-1 / 6-1 , which would be 2/5.
