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

Hedrick wants to enlarge a photo that is 4 inches wide and 6 inches tall . The enlarge photo keeps the same ratio .How tall is t

nika2105 [10]

The original photo is 4 by 6
The ratio of that is 4/6 or 2/3
Since the “wide” is extended to 12, you simply compare the ratio as 4/6=12/x and solve for x. Cross multiply and you should get 18 inches tall
