You have to factor and then get the x intercepts
Answer:
x = 8
Step-by-step explanation:
The measures of the angles in a triangle add up to equal 180°
That being said we can create an equation to solve for x
( note that this is a right triangle indicated by the square. A right triangle has a right angle which has a measure of 90° )
180 = 90 + 5x + 5 + 5x + 5
now we solve for x using basic algebra
step 1 combine like terms
90 + 5 + 5 = 100
5x + 5x = 10
now we have 180 = 100 + 10x
step 2 subtract 100 from each side
180 - 100 = 80
100 - 100 cancels out
now we have 10x = 80
step 3 divide each side by 10
10x / 10 = x
80 / 10 = 8
we're left with x = 8
Answer:
1.861(10²)
Step-by-step explanation:
Proper scientific notation only has the ones place and decimals. To get the same value again, we would need the exponent to be 2 and not -2.
Answer: Vertex
Step-by-step explanation:
To solve this exercise you must keep on mind the definitions shown below:
1. By definition, a regular pyramid is a right pyramid whose base is a regular polygon.
2. By definition, a regular polygon is a polygon whose sides have equal lenghts.
3. By definition the apex (which is the vertex at the tip of the pyramid) of a right pyramid lies directly above the center of the base.
Therefore, keeping the above on mind, you can conclude that:
A regular pyramid has a regular polygon base and a Vertex over the center of the base.
