What is the surface area of this triangular pyramid?

lidiya [134]

Step-by-step explanation:

The formula for the surface area of a pyramid is:

$SA=B+\frac{1}{2}l(number of base sides)(b)$

B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.

$A=\frac{1}{2}bh$

$A=.5*5*4.3$

A = 10.75

Now we can plug in 10.75 for B.

$SA=10.75+.5*5*3*5$

The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.

$SA=$

48.25 in^2

What are the coordinates of the midpoint between the points (-1,4) and (2,-5)

Minchanka [31]

Answer:

(1/2, -1/2)

Step-by-step explanation:

To find a midpoint add the two x's and divide by 2 so -1+2 / 2 = 1/2

add the two y's and divide by 2 so 4-5 / 2 = -1/2

Put the two numbers together as a coordinate (1/2, -1/2)
