A triangular pyramid has a slant height of 0.75 foot. The equilateral triangular base has a perimeter of 1.2 ft and an area of about 0.07 square foot.
find the approximate surface area.

55

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

the answer is 11.2 (i know i’m late)

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
