- Greater than or equal to -10 and less than 10.
4) ![(-10, 10]](https://tex.z-dn.net/?f=%28-10%2C%2010%5D)
Greater than -10 and less than or equal to 10.
Step-by-step explanation:
There are four form of describing that set in interval notation, which presented below:
1) - Greater than -10 and less than 10.
2) - Greater than or equal to -10 and less than or equal to 10.
3) - Greater than or equal to -10 and less than 10.
4) Greater than -10 and less than or equal to 10.
Answer:
Step-by-step explanation:
This is an equilateral triangle.
The altitude bisects the 60 degree angle, so a=30
b=60 since its an interior angle of the isosceles triangle.
e = 4 since the two triangles formed by the altitude are congruent.
c = 8 since the side length is 4 + 4 = .
f = 4sqrt3 by the properties of 30 60 90 triangles.
