What is the area of the obtuse triangle given below?

step-by-step explanation:

the true ones are a b and d

just sum

10 + 10 = 20

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).
