Answer:145
Step-by-step explanation:x-5+3x+25=180
4x+20=180 4x=160 x=40. <k=120+25=145
If you use the formula V=bh you can find the volume of a tranangular prism.
To find the area of the triangle you have to use the formula A=1/2bh
A=1/2(14)(20)=140ft2= Base of the triangle
V=bh V=140x30
V=4200ft2
498 is approximately 500
12 is approximately 10
500/10 = 50
So, 498/12 is approximately 50.
