She spent $12 on notebooks, and she bought six notebooks.
12/6=2
Each notebook costed $2.
Answer:
125
Step-by-step explanation:
the anterior angle is 55
the exterior angle =180 - 55 = 125
Answer:
Length of base (a) = 5 units
Total Surface Area of Pyramid (T.S.A.) = ?
Now,
T.S.A. = Area of four triangles + Area of base
= 
≈ 
Answer:
x=3*2 1/3
Step-by-step explanation:
In order to solve this non-linear equation, we need to move all the terms to the left side.
In our example,
- term 3, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
(x^3 + 3) + (-3) = 57 + (-3)
We need to get rid of expression parentheses.
If there is a negative sign in front of it, each term within the expression changes sign.
Otherwise, the expression remains unchanged.
In our example, there are no negative expressions.
x^3 + 3 - 3 = 57 - 3
The best statement that describes the angle JKL is inscribed angle.
<h3>What is an inscribed angle?</h3>
An inscribed angle in a circle is formed by two chords that have a common end point on the circle. The chord JK and LK intersect in the circle.
The angle ∠JKL is not an obtuse angle because it's less than 90 degrees.
The angle ∠JKL is not a vertical angle because it's not vertically opposite any angle.
The angle ∠JKL is not a central angle because it was not from from the centre of the circle.
The angle is an inscribed angle because it was formed by the intersection of two chords in the circle.
