Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
Answer:
126 in²
Step-by-step explanation:
the surface on the top:
2*1/2*3*2 + 2[1/2]*3*2 = 21
the surface around:
3*8*4= 96
the surface of the bottom:
3*3= 9
total surface: 21+9+96 = 126
GOOD LUCK
Answer:
A Is false, because that'd be 300.
B Is correct, because 9 rounded to the nearest is 10, plus the 300 original.
C I don't know what a unit is, but if it's ones value, then that's incorrect. It'd be 310.
D Incorrect, you can't round and have ".8"
E. Incorrect, can't round and have any decimal numbers...
Step-by-step explanation:
V pyramid = (1/3)*B*h where B is the area of the base
V = (1/3) * 12 * 16 * 7
V = 448 m^3
