Answer:
V = 31.5 in ^3
Step-by-step explanation:
The volume is Bh
The base is the triangle
B = 1/2 (7) *2
B = 7 in^2
Now find the volume
V = 7* 4.5
V = 31.5 in ^3
Answer:9x6−156x5+664x4+176x3−620x2−48x+144
Step-by-step explanation:
Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.
