In a triangle angle A is 23, BC is 10, AC is 13 how do I find C

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
