Answer:
124.7 in²
Step-by-step explanation:
A hexagon consists of six equilateral triangles, each of side a, and we can divide each of them into two right triangles.
So, we can calculate the area of one right triangle and multiply by 12.
The formula for the area of one triangle is
A = ½bh
Step 1. Calculate the length of the side a
Per the Pythagorean Theorem,


2.Calculate the area of a small triangle
The base of a small triangle is
b = ½a = ½ × 4√3 = 2√3
The area of one small triangle is
A = ½ bh = ½× 2√3 × 6 = 6√3 in²
3. Calculate the area of the hexagon
A = 12 × 6√3 = 72√3 = 124.7 in²
2m-5-5= -3m +15
2m -10= -3m+15
2m+3m= 15+10
5m= 25
m= 25/5
m=5
The Answer is b. Hope that helps
Answer:
A
Step-by-step explanation:
All triangles have 180 degrees, these set of measures do not add up to 180°. They add up to 181°, so it is the answer.
