Answer: 87.5
Step-by-step explanation:
Triangle area = base * height / 2
25 * 7 = 175
175/ 2 = 87.5
Answer:
8
Step-by-step explanation:
- An Equilateral Triangle (3 sides) has 3 Lines of Symmetry
- A Regular Pentagon (5 sides) has 5 Lines of Symmetry
- A Regular Hexagon (6 sides) has 6 Lines of Symmetry
- A Regular Heptagon (7 sides) has 7 Lines of Symmetry
- A Regular Octagon (8 sides) has 8 Lines of Symmetry
Step-by-step explanation:
therefore the third angle is 51 degrees
Answer:
a=24
b=10
c=26
Step-by-step explanation:
Perimeter is the sum of the sides (
)
The legs (a and b) have a ratio of 5:12, which means that 
, which can be simplified to 
, where b will be the smaller leg.
The hypotenuse will be double the smallest leg, 2b, increased by 6 meters, giving us an equation of 
Let's plug these in to get one variable:
Now that we have a, we can plug it in to our previous equations to find our other sides:
Double-checking:
Answer:
"The square root of 12 is represented in the radical form as √12, which is equal to 2√3. Since 2√3 cannot be further simplified, hence such roots are called surds"
Step-by-step explanation: I just looked it up-
