How to find surface area of triangular prism

answer:

triangular base: given two sides and the angle between them (sas)

using law of cosines, we can find the third triangle side:

area = length * (a + b + √( b² + a² - (2 * b * a * cos( + a * b * sin(angle)

triangular base: given two angles and a side between them (asa)

using law of sines, we can find the two sides of triangular base:

area = (length * (a + a * (sin(angle1) / sin(angle1+angle2)) + a * (sin(angle2) / sin(angle1+ + a * ((a * sin(angle1)) / sin(angle1 + angle2)) * sin(angle2)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
